I think the same question is asked alot with vintage cars...should we turn it into a hot rod/street machine or restore it too original, some cringe at the thought of cutting up old steel and others jump right in...my line of thought is this, if your going o keep it for years to come, what will give YOU more enjoyment? All fine doing it up as original to sell as such but if you plan on keeping it will this satisfy you? Personally on this occasion i would restore it to original and flog it on EBay vintage bicycles (eg. vintaqge 80s BMX get a **** load of $$$ more than they were in the day anywayz..im sure something from the 1930 would eget you enough to finace a motoered build PLUS alot of change) and do as two above posters suggest grab a cheap to make into a boardtracker....my two cents...either way best of luck mate
