Just checked a pair of Gloria Specials and no go; not wrap around. I will check some Universals (Sport or Mod. 39s maybe), but some may be the wrong reach as juvela mentioned (measure reach at block's center position and provide the data). I only have a Balilla lever or two, but no calipers.
Suggestions given are all great! Certainly check local swap meets/jumbles first.
I suggest checking Subito as I regularly see really decent deals on items just like this where you can buy the pair of calipers complete and have a spare spring (and other parts; make a "best" pair). I'm in the US, but I have purchased a complete bike from Subito which in that case I called the seller (quite old, and the original owner of the "cambio corsa" bike) directly (I know very little Italian, but more ancient Latin) and figured out a way to do it with my connections due to needing pick up, disassembly, packing, etc.; but buying something like a pair of brakes is easy if the seller is willing to toss them in a box and ship (way cheaper than ebay where I had (no more!) suffered more problems than anywhere. Those selling on Subito have been, thus far, really good about dealing with me (and I generally add a little extra coin to smooth the transaction while still making it a reasonably frugal purchase).
