Its a "Portland" bike, made in England, three speed SA thumb shifter, SA three speed hub, looks like the typical English bike of the times....well besides a really laid back seat tube. There are no Reynolds markings on the frame, we only (the last owner and I) think there may be a slight chance its a Reynolds frame but this is soley due to the larger seat tube size. I tried to use a seat tube from an English bike that the last owner told me was the same size as a Sports seat tube but it didn't fit (to small) then I tried the seat tube from my Sports and that was also to small. I don't have the seat tube size from the Portland but will be measuring it today. I know that info is lacking but maybe someone can come up with an answer with it.
