Petter A1 Identification

Engine plate clearly reads type A1 engine number 524249 5 BHP 2000 RPM.

This engine number is outside the listings, is it just a later model.

What would be the year of manufacture.

Will a type A1 service book cover this one.

If this is anything to go by it would make yours an A W series II built between 1945 - 1947

Mine has - A1 serial number 1515202 - on the plate which would make it an A1 built 1956 which I reckon is about right.

mine is 529158 which is 1945-47
so my no is middlish so is a A W SERIES 2 1946
BUT MINE IS MARKED ON PLATE AS A1VO AS IS A TVO MODEL
SO THE LIST IS GOOD FOR DATING INFO
THANKS KEV

THE A1 MANUAL
SHOULD BE GOOD FOR THE JOB
AS THE ENGINES ARE ALL BASICLY THE SAME INTERNAL
just some castings varies and the compression alter from petrol to tvo slightly
but the manual i have is a a1 a2 w1 w2 petrol and vapourising oil engines manual
the horse power difference is that your 5hp is 1650 rpm
and my 1.5hp is 750rpm
so a1 manual will do the job for you as nothing really changes from 1 1/2 -5 hp apart from boring diameter of cylinder bore for piston
but this should be stated in your manual anyway
if your still sruggling for a manual for it PM me ON HERE
and we can internet exchange my " PDF " manual to you
thanks kev

Hi All,

The best way to get Petter Dating (engines by the way ) is to drop a snail mail to the guy below, Send as much detail as possable with a couple of pics and he can date it and also let you know who it was first supplied to.

Hedge End
Southampton

If you like drop me a line after you have details of your engine i will add it to my list and we can try and get a list going here, I tried on another site but got very little response. if i get a decent response i would publish it on here.

If anyone wishes to be include there engine in the list please feel free to pm me your engine details. At the moment i only want to concentrate on Petter A , and Petter A1, I would probably try and include other Petter engines as time goes on.

Hi I have just bought an A1 ser 1544605, won't have it for a couple of weeks though.

the address you gave is not far from me at all, I live in Locks Heath and grew up in Botley, the post code should be SO30 though, I am pretty sure I used to deliver papers to him when I was a kid lol. How do you think he would respond to a visit in person?
Wouldn't want to be rude etc but would be nice to meet someone who knew something about the engine I have now bought.
Many thanks
Andy

Andy might be best to post a letter first and say your local and ask if you could call in to discuss it rather then just turn up on the door step. I'm sure you'll understand that if everyone local turns up on his door step he'd soon stop showing his address. Also if you get an invite you might get a tour of what he has, as for security reasons I wouldn't be showing anyone that just turned up on my door step what engines I have and I'm sure he'll be the same.
Don't get me wrong I'm not saying anything bad about you just suggesting the best way to go about it in my opinion.

Stu.

Hi Andy,

I agree with what Stu has said, it will save a lot of embaresment for both partys, im sure he would be more than happy to meet you to discus your engine and the possability of showing his collection.

I have checked the post code for keith in the SE magazine and it is as i have put it, im not saying your wrong but im gonna leave it as it is at the momment until im told diffrently from Keith or it is printed in SE mag.

Many thanks
Paul

Ok thought it was worth asking for those reasons, you never know until you asl lol.

Re postcode, it is definately a typo in the mag then:
Tesco Express
Tanhouse Lane
Hedge End
Southampton
Hampshire
SO30 2SZ

is the tesco express 300yrds away, Botley/Hedge End are SO30. As said a typo then. Only reason I point this out is because I wouldn't want peoples info being lost in the post.

I really can't wait to get my new toy, realy quite looking forward to getting her to a rally, but she will need a good check over and a lick of paint first, also looks like my Dad is bringing some of his engines out of the woodwork for some play time so we are hoping to exhibit at a few of the Hampshire rallies and I would hope to meet some of you there.

Also re posting a letter for dating, is there a fee presumably and if so how much/what form? Would like to get all the info I can for rally info and personal knowledge

Andy

Andy,

Thanks for the post code info, cant get more detailed than that, i will adjust it as necesary.

Look forward to seeing some pics of your engine and gat your fathers engines out there as well.

Keith dosent charge for this service, but send a SAE for a reply,

I’ve just purchased a derelict Baker & Hunt walk behind hedge cutter which has a Petter A1 engine with the number 538236. Would anyone be able to date the engine for me?
Would be really grateful. Many thanks Richard

Hi Richard and a very warm welcome to the forum.

To avoid spam you should not use your email address as username. To change just click Profile and Username is the first item.

The go-to-guy for Petter dating was Jim Perkins, but sadly no longer with us. Maybe contact Internal Fire museum?
FWIW My guess would be around 1948/49

Paul,
Can I please refer you to the following page of Internal Fire.

Hi Many thanks
Yes I’ve tried internal fire but unless you are already logged in with an account there is no access to records. Apparently the archive is closed down due to a lack of donations. Great pity.
I’m thinking the engine must be something like late 40s early 50s. The machine it’s on is patented 1928 but I can’t think it’s that old. And I can’t think it’s had a replacement engine as being a hand held hedgecutter I can’t think it’s done much work.

Many thanks Maurice for your advice. I’ve taken another look at it and it’s definitely an A1 and 3bhp. The machine it’s on was actually patented in 1936 so it’s obviously an engine older than that! I’ve attached a photo hoping that I have managed to o attach it! Richard

Another fearsome looking piece of agricultural machinery !! Please start a new thread in New Projects/Restorations when you get going

Forgot to say I have manual if you need a copy

Ah many thanks but what I’m really after is the name of a company that sells spares for an A1? And the right colour paint!

Hi, I've just had a quick check and it seems as though Stationary Engine Parts stock some spares for the Petter A1 series of engines. If they have what you require I don't know but it would be worth you giving them a call.

Neil

Thanks a lot Neil.

@Woodsman, may I bother you with a copy please. Im a seargent in the SAAF and we have an old A1 that needs reassembling and a manual will be of great help.

Email sent.
Please start a new thread in New Projects/Restorations and keep us posted.
Good luck.
