A friend of mine recently picked up these early Ford Lockheed style hydraulic backing plates. He's been working with this old Ford stuff for 50 years and has never seen another set like it. What makes them different than the regular '39 to '41 hydraulic backing plates is that the the bottom halves are ventilated. They have Factory Ford script stamped on them and they look like factory stampings, not modified hydraulic backing plates. After looking closely at them myself, I can't see any evidence that they were cut, trimmed and ground. They are for standard 12" drums and have grooved brake shoes. What were they used on and what years were they made?

Here's one of the pictures posted on the HAMB.

Look like the first series Ford hydraulic starting in 1939 (adjustable lower pins) that have had the edges neatly trimmed away(?). Or?

Severely trimmed stock brakes. Surprised they didn't drill the heck out of what was left! Interesting grooving on the shoe material too.
 
Typical of what was done for a Roundy round stock car back in the day {1950's to early 60's} Usually these would have full floating hubs {3/4 ton type} on the stock Ford spindles. The brake drums used were usually wide five early Ford bolt pattern brake drums or on the better builds modified finned aluminum Buick brake drums on the Ford wide five hub. The Ford backing plates were modified so the brakes would cool off faster. Just some good old back yard Hot Rodding use stock production parts with some slight modifications as needed.

Thanks for posting the pics, I tried and they show up on my computer but not anywhere else. They did a really good job on them because there's no sign of them being cut or ground that I can see. The consensus is that they are modified originals so I'll go with that.
 
RR has it, spent 10years at Danbury. Tried everything, some worked , some didn't. Part of the learning curve.

I would think in my world those are off some piece of industrial equipment . As for roundy round racing ,yes I bet they were great for that but I don't think they are back yard made. Tim
 
I stand corrected . After doing a little research I now see how it was cut down from a 1940 style backing plate to look as it does. But I will say they did a good job of it as it looks factory. I need to listen more and learn, Tim
