Pre-war BSA M24 Spare Parts
As we are dealing with bikes that are 80+ years old, New old Stock spares are in very short supply, and anything available tends to be expensive. 
M24 specific items in good condition, such as Cylinder heads & Barrels trade for £1000+, and some cycle parts such as rear stands and fork yokes can sell for up to £200+.
Many cycle parts were common to other 1937-40 pre-war M-series models, including the war time WD M20, and one or two specialist dealers may still have limited stocks of new WD parts.
Copies of the original parts books for 1938 & 39 BSA models are an invaluable asset when looking for spare parts. Reprints are still available from the National Motorcycle Museum bookshop as well as copies of other useful BSA literature such as Instruction booklets for individual models. These will provide illustrations of all parts with original part numbers.      It is useful to have a copy of BSA Service Sheet 703, Workshop data all models. This can be downloaded off the internet.
