This amazing barn find BSA WM20 500cc motorcycle has been stored in a Swedish barn since the 1950s and remained untouched since recently discovered in 2020. This is a completely original motorcycle, and whilst not currently running the bike has retained all the original patina from its army paint scheme and markings.
Full restoration or retain the current patina?
Many would argue that conducting a full but and bolt restoration on this bike would ruin the originality of the bike, which represents a true survivor from the 1940s pre-war era. I tend to agree with this view because there are already fully restored BSA WM20 examples out there if you are looking for a very clean bike.
Whoever wins this bike within the auction I hope they decide to keep the original condition and perhaps only restore to the point where usable again as a demonstration bike, possibly a museum piece to celebrate motorcycles of the WW2 conflict.
