I am at present trying to sort out some sort of dateline for pre-1980s De Rosa frames with pressed lugs. I have collected quite a number of pics from Wool Jersey, Flickr and other places which is beginning to bear fruit. De Rosa frames of this era are quite rare - and were made in much smaller numbers than Colnagos...
De Rosas of this era are really rather uncommon and it seems that many have been extensively modernized - I tend to think that many owners hang onto them for many years. However there are a number of features that will help to point towards a year...
Therefore I am looking for pics of De Rosas with pressed lugs - detail pics help to sort out these details - seat lug and seatstay cap, head lugs, fork crown, chainstays, rear dropouts and fork crown.
I would really appreciate it if CR members can get in touch with pics and if any have confirmed dates these are even more important... I can also send to anyone with an early De Rosa a simple questionaire if they cannot or don't want to take pics...
I may well eventually attempt a similar project on 1980s ones... so piccies of 1980s ones will be welcome too.
