just found out that my boss rides a very early 80's Marin ..... he doesn't know the model , but it's duck-egg blue and almost all original ( he says ) I will get some pics tomorrow and get all you experts on the case ! think i'll have to make him an offer he can't refuse if it's in good order .... i've seen it from a distance - it has a "sit-up and beg" stem - short - very small diameter tubing ...... looks like bike number 4 if he agrees to sell
