Ahhh nice, thanks for the link, very interesting.

Mine does have Campagnolo horizontal dropouts.

I think there's a tiny chance it's a Juvela - this is the only frame I've found in all my searching that has the same Bocama lugs, Nervex fork crown, horizontal dropouts and chrome pattern Mondia Juvela 163475 but realistically the likelihood is that mine is a Mondia. Although I will never know for sure! I am also glad not to be searching for a Juvela headbadge, it's bad enough looking for a Mondia

I may have confused things by going on about it not having Campagnolo vertical dropouts. I think Cyclo-Cross and Criteriums had vertical dropouts, so this is largely why I've ruled out those models (and the chrome pattern).

In the 1977 article on velo-pages it says the new Criterium Prestige will have short horizontal dropouts although their test model does not. It doesn't say what the test model did have but squinting at the pic I think those are vertical, and the yellow Criterium frame I found and posted previously also has vertical dropouts. [For what it's worth the Juvela Criterium also has vertical dropouts.] Assuming the Criterium Prestige is the Criterium but with better components, maybe they just sent across an existing Criterium frame but with the Superleggeri pedals, Fiamme yellow label rims, Clement silk tyres, or whatever bits were the Prestige upgrade.

N.B. the Cyclo-Cross models also had the vertical dropouts until the late 70s when they were replaced with the short horizontal dropouts Mondia Cyclo-Cross bicycles, RB gives more details in his timeline as well, including the option of having long horizontal dropouts from 1976.

I have the 60s edition of the headbadge with just "Mondia" in script but I would prefer the period correct badge if possible, I'm sure one will come along sooner or later.
