frame bits -
head lugs are BOCAMA 20's series feature cut
there are three 20's series patterns, one would need a front view to determine which of them were employed
head lug nozzle cut is BOCAMA /I
seat lug is BOCAMA pattern H
dropouts are NERVEX nr. 1036 G
shell not shown well enough for an ID
track style fork crown may be one of the Georg Fischer patterns, just a thought...
