The JAP engine are said to be from 1961 but I don´t really know.
Drott GearboxFrame are probably made in Finland as the bike was found there.
It has been stored in a livingroom for about 15 years and before it was placed there it was started and tested. It was after that drained on oil and has not been started since.
Are now in my office and it has given me great joy to look at it every day but are now ready to sell it.
Price 4900 euro.
