Saw a lot of them in central Florida, back in the '50s. I had one briefly, back in late '58. It actually belonged to a friend and I mounted it on my '51 Ford flathead six for about a month. I did notice a fuel mileage increase and it was a little faster in a 1/4 mile. If I remember correctly, I ran a 19 second 1/4 mile with the stock Ford carburetor and about 3/4s of a second faster with the Fish. I always wanted a set of them...like 3 for a six cylinder engine, but never did get 'em. Someone in england made then for a while after Fish went under, but I assume they're gone now, too. If I had a chance to buy one, I would.
