Help ID’ing beacons (750 Holmes)

A friend of mine bought a 74 Peterbilt to restore to look like a wrecker his dad ran early in the business. I’m trying to locate the correct lighting for it. I’m inclined to guess these are either Dietz or North American beacons. Any ideas? I also suspect those are Petersen MFG flashers on the headache rack...

Dietz 2-11 and 7-11 models on e-bay very frequently. Prices often vary, there is at least one amber one now there.. Split dome versions, not so much..

I've got a pair of "just freshened" 211's sitting on the shelf. 1-red and 1-amber. Drop me a note at hyper-lites-corp@hotmail.com if they are of interest. They were found laying on the roof of a '61 Falcon wagon in a garage, collecting dust. Here's a pic as found...

One amber unit has already been snatched-up by a colleague for his '64 International snow plow. I completely disassembled and mechanically went through all 3. They're working 100%. Cosmetically, is where the hard part comes-in. The domes on both amber units were all kindza cracked-up. I repaired them but if you want good, I have good amber dome to go with, for a bit extra. The bases are not pretty but not beat-up...again YOUR elbow grease, is the key. The red unit's dome was just fine for a working piece.

I think I might still have a NOS amber Deitz dome kicking around.
PM me if of any interest.

I seem to recall that the split dome was an amber dome painted with transparent red on the inside. If true, amber domes are abundantly available. Or it could be a filament of my imagination...the years have not been kind to my brain cells.

Nope, it's not a fig newton of your imagination. Dietz's red-amber split domes were amber domes with 1/2 of the inside of the dome painted with transparent red paint.

The beacons on that tow truck are definitely Dietz 211 or 7-11 up high and a 240 or 7-40 on the right side of the bed.

That is really interesting to learn!! By chance is there a consensus that Federal Signal and Whelen did the this process as Dietz did?

Sent you a couple emails about buying those.
