hope you measured frame's brake centres prior to sending off for those Pietra 51's...
their centres are 50.5mm and 64mm
either an Ambrosio Champion steel or alloy stem would be plausible, as mentined previously
bar should be an Ambrosio Champion alloy
checked for you and there is not a set of Frejus marked Gaslo caps on ebay.it this week
here is a Bianchi set as an example
