The power transformer (part number 25807) in the B15 is the same used in various 5 valve AWA/Hotpoint/Westinghouse models from the mid 50's through to the early 60's.

In fact, the B15 was a mainstay throughout the 60's & was still in production in 1970!

You could swap the front over if you prefer the Westinghouse look.

I would not be surprised if the Transformer for it & several other brands was the same & came out of the same factory. E.g. Many sets had tuning gangs made by Stromberg Carlson & EMMCO made made radio's & lots of parts for them & for other manufacturers.

Yes well I recapped the ebay one and it works like a treat, now today a transformer arrived in the post from Kevin Chant, who helped me out with an old one that he had for nest to nothing, so very grateful... I fitted it and wired it up, replaced the electrolytic's and now it works fine again! Happy about that as this particular one is not actually an AWA Radiola, although the case and chassis are identical, it is branded "Westinghouse" so although most likely not rare in itself, it is distinctive!

An in-line fuseholder (a fuseholder that has wire pigtails) would be good insurance. You could hide it under the chassis. Select a fuse about 1 1/2 times the amps the radio usually draws off the mains. Something like this:-
