Barry,
The Gotha ads I've seen were for conversion parts.They had a kit to convert the stock intake to dual carbs,( it was basically two flanges you welded onto a stock intake with a blockoff plate for the stock carb location), and a kit with a flange to split the stock exhaust manifold. Sort of a poor man's performance line.
I'd have to look at some of my old mags to check out if they offered other stuff, can't remember now. They were based out of Harvey, Il on the south side of Chi. so you'd think some of there goodies would be around here. There was an old Deuce coupe around here that had an Olds V-8 with Gotha aluminum valve covers and I believe intake a while back.
