thank you for the additional information and photos

the combinaton of a 70mm shell with a three-dog fixed cup tells us we are in Italy

the cupset appears it may be OMG brand, spindle is from another maker which is why we saw all of those threads showing in assembled image, the A-8 marking is suggestive of Britain, does anyone recognize the _ASTMAN name?

pillar size suggests a quality plain gauge tubeset

frame bits -

bottom bracket shell appears to be Agrati item nr. 000.8507

dropouts are Agrati item nr. 000.8002

bridges are likely Agrati as well but do not have stock numbers for them

one maker who combined Prugnat 62/d lugs with some Agrati bits was Rizzato

however, serial placement is wrong for a Rizzato product

the uneveness of the marking makes one wonder if it may have been made post-manufacture, perhaps put in by a licensing agency for example

one check you could make is to remove the paint from the drive side of the seat tube about five or six cms below the seat lug. if cycle a Rizzato product a number will appear:





in serials of this pattern the first two characters indicate the year of manufacture
