Well, I'm now tearing apart my parts chassis- I think it is from a 38-3, but stamped inside is 38-1754. Details match a 38-3: 9 tube, 3 band, magnetic tuning. I'm just wondering about the 1754 stamp... Any ideas? Or is it just a miscellaneous stamping? I know my 37-650 had 37-650 clearly stamped on it in several places...

Mainly tearing this one up because it came as a parts set to me, but space requirements demand I take it to parts. No cabinet or speaker- I just was given the chassis, with a couple tubes on it. Luckily one was an excellent 6F6G I needed for the 37-650. Also, I believe it has the same power supply- although the numbers are different.

Lots of bits, however... Now I happily have more bakelites to rebuild for stock, some more junctions, rf coils, variable caps, tube sockets... Just have to figure out what to do with the magnetic tuning parts. Keep them or flog 'em? I'm having fun

I'll bet that stamp in on the RF sub-chassis, right?

That's the part number of the sub-chassis assy, not anything to do with a "model number."
Philco sub-bases and sub-chassis' were designated with the 38- prefix.

See this Service Tip from my site about Philco's part numbering scheme:

PHILCO SERVICE HINTS & TIPS - NUMBER 34
Philco Part Numbering System


Many people confuse Philco part numbers that start with 36-, 37-, 38-, 39-, etc. with model numbers, due to the fact that Philco started using the model year as a prefix to it's model numbers in 1937 on up. There's a Service Tip on this in the TIPS section as well.

You hit it, Chuck! When the light hit the back of the chassis main frame just right, I could make out the original 38-3, code ??? stamp, where it was missing... I could see where the ink had been, but it was no longer dark. Odd thing- my 37-650 had that number(37-650) stamped in the same type large number in several places, similar to the number I was originally referring to. (These are rubber stampings- not metal stamps)
