That looks like the originals, martin! Sure would like to run up on a set like that!
The carbs, set up on a side-draft intake, in back of the Fishes, are zenith 8810-Bs. I had a set of three on a home-made intake, bolted to a 235 Chevy and that sucker screamed! They were easily tuneable and, set up with progressive linkage, delivered great mileage.
I recently gave them to a friend to mount on his 240 Ford. They had sat in a shed for over 35 years. Being unable to find a repair kit for them, he gave them away.
