Silca Impero frame pump, what size? And questions about Silca history.

How do you calculate the length for a Silca Impero with a Campagnolo 1030/2 pump head, for a snug fit between BB and top tube?

The bike that I am looking for a Silca pump is 62 cm C-T and has a inner seat tube measurement of 55.3 cm.

But when was the frame-fit variation with a concave handle introduced?
Good to know when trying to build period correct. Maybe I should go for a shorter/standard length pump and an umbrella clip.

Some info at Yellow Jersey:

Silca have a rough guide for the classic model:

Going strictly off memory, which is hazy but, I don't remember seeing the handles with the frame tube fit concave until sometime mid 70's, I think. Finding those longer ones can be sort of challenging. Usually the seller will give you the compressed and un-compressed lengths. But not always. I have a couple of 62's also, but I use the umbrella clip and old style Silca pumps.

Kinda the same here. I haven't seen many (if any) photos from early 70s or older with a frame fit. If someone has a link to a untouched bike that brakes this claim, please post.
