The current model Record Pista cranks are the same as the lazer etched and engraved models (other than the logo on the cranks). They also did one with the crest screen printed (like the current model)
Campagnolo have not changed the design since the 90's.
I have 3 sets... (2x 165 current, 1 x 170 printed crest), non are forsale... sorry.
