May sound a daft question, what is the correct type of locking washer used on vintage pre-war BMW bikes? Is it star washers, tab, nylock etc.
Any vintage bike that has not been well kept over 80 years is going to end up with an assortment of nuts, bolts, screws and washers, basically because the originals were lost or mixed up and the nearest one to hand made do. Interesting to find out what BMW of era used.

The "Ersatzteile" parts

The "Ersatzteile" parts manual should list the size and type of washer used on each and every bolt. Nylocks didn't exist so it should be a variety of wave washers, (federscheiben) and inner star toothed washers, (zahnsheiben). You will find that if it's used on the frame and sheet metal it will generally be a star washer. And you might as well use stainless.

Here is the R51-R71

Here is the R51-R71 Ersatzteilliste. It is an old scan of a scan but it is mostly legible. I have an original in good condition that I keep meaning to scan, but have not found the time to do it yet.

You will next want a good German-English technical dictionary. Two good ones are:

Two Wheeler Technical Dictionary (English/German/French) Beatrice Couzereau ISBN 3-87073-054-4
Technisches Taschenworterbuch Henry Freeman ISBN 3-19-006212-9

I have another technical German dictionary somewhere, but it may not be unpacked yet.

Cheers,

Bruce
