I don't ever think I will get this pedantic about any motorcycle. I'm just glad it has what mostly looks like the correct parts (albeit Bubba-ized in places). I'm no stickler for absolute correctness. Oh, and for your visual enjoyment, an image before the "restoration" by previous owner...
I have just send you some information about your BSA. Your BSA left the factory in 1941 and according to the photos I have with tank numbers close to your BSA it didn\'t had the valanced mudguard any more.
According to my calculations your tank number would have been C4356149.
It seems your BSA shouldn't have a valanced mudguard but still have the ridge on the middle of the mudguard. These mudguards are just as hard to find as the one you have now.
Hi Cas...Welcome to the forum...Once restored/refurbished you will find your M20 will give long and reliable service...(with or without the chrome.. )
I have to say I'm in total agreement with Rik over the question of 'fixed specification'...
M20s were completed at the rate of one every ten minutes at peak production with more than one assembly line involved in the work...
This type of production is simply not possible unless the system that supplies parts to the assembly lines produces the right parts in the right quantities and at the right times...
I worked in production engineering at a factory that manufactured automatic lathes and milling machines and there is no way this could have been done in some sort of 'ad hoc' fashion....Ian
