There is nothing stemped on the frame but the serial no.
I spoke with friend of mine, whom use to work for a local bike shop, and he told me that it must be a marin.
now, i find myself looking for an early models pictures of marin, to match up the geometry.
any more tips...?
btw
I have just finished sand clean it and repaint the frame in light green.
I will post some pictures later.
