Hello, we have a sieber bike up for auction on ebay. It is from the 1930's or 1940's we believe and was purchased recently from the original owner's son . The original owner raced in the 1930's and 1940's and his son believed this bike to be from that era. The auction number is 6502646436 and we have packaged it with the wheel assemblies separate so it can be shipped more economically if wheels not wanted.
Hope this is something you could use......we have a reserve of $250 on the bike. Thanks for your interest and best of luck if you decide to bid!
