On the front of my model A dropped axle, are disc brake calipers they have casting number E64328816 on them,they didn't show up on google and my local parts supplier does't know them either.
The non-ventilated rotors leads me to believe those are sourced off something older. You haven't posted a full pic, but those look a lot like older Volvo (late '60s/early '70s?), those were a semi-popular early disc swap before discs became common on American cars. If that's what they are, you may have problems finding replacement parts.
They do appear to be Volvo's, early Jaguar's used those calipers also. Check with Moss Motors in San Luis Obispo, Ca. for parts.
SD I haven't seen them for years so I can't say positively that they are Volvo but many years ago a friend of mine with a chassis shop used Volvo 122s disc brake components for some of his conversion kits and I know other guys used them. Like others have said, not a lot of replacements to be found easily nowadays.
Here is an old thread on what I believe is the same caliper setup . https://www.jalopyjournal.com/forum/threads/need-help-iding-these-disc-brake-hubs.1005222/
Your spindles probably have a 1/4” or so spacer to move the inside bearing toward the outside. The inner bearing will be the early Ford and the outer Volvo. Grease seals are National 224046 Replacement parts? Really what will you need? A caliper might be hard to locate but rebuild kits are available Just about all aftermarket kits moved on to vented rotors, but solid worked for Volvo, Jag and a host of others for years, I’d keep ‘em.
I went out to the garage and looked at a set of 122S rotors and calipers on the shelf. (I have an innate ability to keep stuff until it is worthless.) Some of the cast numbers weren't absolutely clear. For the number in post 3 mine have (E64326816).(The first 6 looked more 6 than 8.) For pictures 1 & 2 in post 8, my number is ('some unidentifiable lump'4325793). In picture 3 of post 8 I have (DA1?698).(The 6 was a best guess read.)
