hi , help please as I thought I had this all worked out until I read the Book Lister D Restoration , The way I thought it was is the Hovis loaf mag = RS1 and the other full front plastic cap = SR1 , and google search etc = that . But reading the book it is in reverse to that , but I most likely have it wrong , I am sure you will put me right .

Hi Gerry bongo, yes you are correct in thinking that the loaf of bread lucas is the rs1, and the later full plastic end cap mag is the sr1, it is easy to mix them up though and could be typing error, hope this helps, regards, mister engine1932.  

Thanks for that , i did think it may be a type error .
