I didn't know that Philco was still using Mershon condensers in 1932? I figured that maybe they phased them out late in 1931 since the early Philco 90s had them but the later production ones did not. It wouldn't be to hard to recreate some suitable facimiles out of plumbing parts, some 1-1/8 to 1-1/4 inch copper pipe, an end cap, and a threaded nipple if it's the type of condenser held in with a large nut, a propane torch, flux paste, and 50:50 solder. Some building salvage yards like Habitat have new and used plumbing parts. That being said a pair of aluminum ones would look quite acceptable in there, when I have a set with period type replacements in it I usually leave them alone if they fit mechanically.
