Some observations:

1. Philco did not use metal tubes originally. Philco was feuding with RCA throughout the 1930s. RCA was a heavy proponent of metal tubes. For this reason, Philco refused to use them, instead having Sylvania (who made their Philco branded tubes for them) make glass octal tubes with ST or "taper-top" glass envelopes.

2. Radio manufacturers did not attach tube sockets with screws; they used rivets.

3. Philco used phenolic wafer sockets when this chassis was built, not the black bakelite Amphenol sockets.

4. The IF transformers are not original.

5. Philco did not use octal tubes in their 1936 radio models.

I find it very odd that what is obviously a 1936 Philco chassis would be inside a 38-643 cabinet, unless (a) the chassis was stuck inside backwards or in a manner that the control shafts did not protrude through the front panel; or (b) the front panel was redrilled to accommodate these control shafts.

Can you post photos of (A) a top view of the chassis), (B) an underside view of the chassis, and © a photo of the cabinet, please?

I think the chassis is a heavily modified model 640. It has four bands on the dial scale, and shows evidence of once having a vertical mounting power transformer. It is probably not worth restoring - in my opinion.
