Factory drawing of 1937 Pre-production M24 engine
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.
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 WDM20, and one or two specialist dealers still have 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 www.brucemainsmith.com as well as copies of
other useful BSA literature. These will provide
illustrations of all
parts with original part numbers.
www.russellmotors.co.uk in Battersea, SW London provide a
useful downloadable catalogue and price
list for the WD M20 and
keep a good stock of suitable, and often new old stock parts.
www.draganfly.co.uk in Suffolk, UK also keep some pre-war BSA
parts. Again you can download
a very comprehensive catalogue
full of useful drawings and part numbers for early Gold Stars, and
http://www.cornucopia-enterprises.de/ based in Germany have WDM20 and some 1930s spares, again with a comprehensive online catalogue
keep a stock of parts and occasionally I will have new reproduction parts made using original patterns and may be able
to help. See For Sale & Wanted page

M24 Petrol tanks made in India -
BEWARE - These may look good from the photos, but one recently sold to Australia had the front brackets in the wrong
position, mounting holes for kneegrips & badges wrongly spaced, and it did not fit properly. They may be cheap, but you
get what you pay for.
