Yep, the binder bolt area looks solid (no open space), so it must be investment cast. BB shell is a Gargatte I believe ("+GF+" markings), fork crown looks to be maybe IC too? Who cast the lugs? Microfusione?
Greg- Mario while at Masi was working with Microfusione regarding IC lugs for them.
Solid Seat lug ears on an Italian bike have nothing significant to say IC, Got to see the work of Masi in the raw pre IC lugs both from here and Italy, a section of tubing was brazed into the lug ear section, voids filled with brass, then sculpted back, when I saw the process , I thought wow, that is labor intensive!
Mario used the same BB & fork crown as he had used at Masi. just a lot of filing & machining.
I know his early frames used Bocama lugs, would love to see the very early and very late to compare.. Best chance to get them together at one time...'06 Cirque theme? Or, best at VR6 perhaps.
My '68 Foirelli Coppi has these solid ears, as do many other Italian bike of the period and prior.
