The old Record Sprint had a compact crank (the gold one, not the black one) it just didn't have compact rings. In other words it's a 110mm BCD so you could just go out and buy a pair of compact rings and bolt them straight on....
Oh hold on the very first generation did not have detachable rings. Which do you have?
I think the smallest ring you can get on a compact is a 34t.
You can fit a triple; new bb, chainset, a triple front mech and a long cage rear and you're there.
If you do have the 110bcd version then the original rings were steel too so you would lose a little weight by changing them for some alloy compacts. Well not you personally but your bike
