Galli was an Italian brand that produced what were more or less copies of Campagnolo's stuff. Will probably
perform about as well as Campag stuff from the same era, but interesting because it's quite unusual.
As for the frame, looks like a Belgian Diamant to me. Most people in Belgium over about 25 seem to get quite nostalgic
about Diamant - I think it was a bit like Raleigh, the sort of bikes most people would have owned at some point.
If it's Reynold's 531 it's good stuff. Better bikes had the whole frame and fork made from 531, cheaper ones
just the main tubes (head tube, seat tube, down tube)
Nice neat frame, Prugnat / Bocama lugs and campag dropouts, I've got that (Cinelli) semi-sloping fork crown on my 70's Falcon San-Remo
Nothing at all wrong with Galli stuff, like Zeus it sort of suffered being in the shadow of the big boys.
I'd ride it
Nice reactions! I'll keep the bike original as it is, it's nice to give some attention to less familiar brands/groups than buying together the next one-in-a million super record group on ebay
. And budgetwise, this also helps a hand
About Diamant: to me it looks like Johnsqual stated. Diamant is more or less for Belgians what Raleigh is for UK-people: it's nostalgic, it's well-known and wide-spread. I just want to make sure in one way whether this is a Belgian, German or Italian frame...
