Autolite 4100
Prolly around 480 CFM if it's for a 260
Measure the bore, they were available in 1.08" and 1.12" venturi

Thanks for the link, now i know where to look for numbers on it. it says 108 inside of what looks to be a clock, guess thats the venturi size? and the date on the bottom is 6-65, the other number is 6A-AC. vacuum secondary's? also looks like the brass vent tubes are missing from the top.
