If the model number and the tube placement diagram is correct then the set has gone through some butchery. The set looks like it had push pull 6F6s output tubes, the socket of one of which has been covered by a choke or transformer of unknown purpose. The power transformer is also a replacement, the original had the rectifier tube mounted on top. However in looking at the set one has to wonder what did they use to replace the rectifier tube since it doesn't appear that they relocated it to another part of the chassis, selenium rectifier maybe? Hopefully it wasn't hacked up too much underneith, it would be nice to put it back as close to original as possible.
At first glance the set appeared to be a Philco 38-610 in perhaps a 38-7 or 38-8 cabinet but the cabinet is different from those as well, it's deeper from back to front and has veneered panels where the solid wood parts would be on either side of the speaker grille. It's almost like it was based on the 38-2 and a 38-3 cabinets but with a different grille.

P.S I did some research using Ron's ever so useful gallery, it appears that this set (or at least the chassis) was an export version of a 38-5, possibly the main difference was the power transformer being designed for 240 volts at 50 cps. This is good news because it means that it should be possible to locate the missing parts, other then an original power transformer for an export model which likely would have been similar to the one in Ron's newly acquired 37-670.
