I've used Silca pumps for a long time, and my experience is that the chromed pumps were a strange and final variation of the Impero. The pump head, IIRC, doesn't come off, so you can't put on a Campy head. ... although I've been using my stash of the chromed pumps for so long that I forget the specifics. I suspect that I tried to remove the head, because it's really not very nice.

With that out of the way, I do have these on a few bikes. Two are on seat tubes of 62cm c-t frames, so they were made in large sizes.
