The Sams folder (schematic, dial stringing, parts list) for this radio is on my website:

This is a transformerless radio and if you intend to run it out of the case for testing, you MUST use an isolation transformer for safety. Is it a field coil speaker? PM speakers are easy to replace. I have the tubes, but there are many other sources online. The dial glass (or plastic cover) is unique and will have to come from a junker. I may be able to find one at the Antique Wireless Association flea market on Thursday. The transformer is probably OK if the resistance readings check out per the schematic.
