In an older topic a hand-change gearbox is mentioned for these: http://pub37.bravenet.com/forum/static/show.php?usernum=3155626639&frmid=16&msgid=1098293&cmd=show
But period film show some M20 (or look alike) with normal foot chance gearbox.
Any idea on how many of the BSA singles were initially ordered by bthe pre-war Dutch authorities, next to the V-twins?
Not for the rivet-counters, but I may consider doing a WM20 up as one of these earlier ones, so could do with all information. Photographs anyone?
In the book "The Other Battle" by Donovan Ward, I found that the company (BSA) supplied the Dutch army with more then 1750 motorcycles of the 1000 cc and 600 cc types in the two years before the occupation. It doesn't say how many of each. I have lots of pictures of early M20's, here a "Dutch Pattern" one now owned by Herman.
Did the Dutch buy any M20s, I thought they were all M21s?
The 1940 BSA Factory Ledger for WM21 Engine numbers shows some WM21s going to "Delft" with "f" foot change gearbox's but for most it doesn't say either way.
It could be that the KM21s in the previous book had the hand change box's??
I always preferred Bracebridge street products, so do not blame it on me. But since working on Preston's WM20....
So the Dutch only had M21's? Anyway, I have got a M21 bottom end somewhere, so might use that to get some more out of the engine, without the need to buy one of Ian's Big bore kit and to stroke the M20.
