Hello and welcome.

Assuming you mean the large console (floor model) radio, it is a Canadian model 53 (CHASSIS TYPE 53 on metal tag = model 53). It does not correspond to any USA Philco models, so finding service information will be difficult. Not impossible, mind you, but difficult. You will need to obtain the Radio College of Canada set of manuals in CD format, sold on the auction site.

We normally do not allow ads in this section, but since this is informational only - you need the information and I am only glad to pass it on to you - here's a link where you can get your own CD.

Good luck.

Edit: There is a black and white illustration of a Canadian model 53X (your set) at this page in the Philco Library section of this website - scroll almost all the way to the bottom of the page to see it:

You will also note by looking at this page (also in the Philco Library) that the 53X/53AX is a 1942 model.
