Swap meet table or nearest dumpster. Sorry they were a terrible carb, full of aluminum shavings etc, didnt meter fuel properly.

Look like a very early 750 Mighty Demon Vac Secondary.
Demons had questionable build quality but I have successfully made even ones with the dreaded metal shavings work.....you just need to go through it.
I just shipped a 1971 Demon 340 with one of these on it and it worked like a charm.....I recommend changing out the nitrophylic floats for Holley brass pieces....they float better and I have found better bowl metering at 7psi.....plus you can see them through the sight glass much easier.
