Thanks for reading the thread and for your comments, which could well be correct.

It's some time since I looked at it, so as soon as current projects are out of the way, I'll get it down from the loft, and make it my next project. It's an interesting set - the one piece Millboard back & base can be removed to reveal the top and bottom of the chassis for ease of servicing. Given the poor state of the 'cabinet' - which is really just a front panel with two small separate end panels in contrasting veneer - I'll tackle that before the electronics. I rather like the styling of the radio, albeit electronically, it's quite basic and uses an auto-transformer for economy, so it has a live chassis.


When I have something worthwhile to say about it, I'll give an update.

There's one on display in the Science Museum, but I'm not sure why in particular:

It has something going for its unique styling that various other Murphys don't quite manage, IMHO. Some of their models just look weird, this one looks interesting!

I suspect it was chosen for this quality.

I have one of those Murphys. The veneer is ok, but the wiring is the crumbly rubber type that Murphys of this period always seem to suffer from. It also seems to be based around whatever valves they could get at the time as IIRC the output valve is a big prewar style thing, whereas the rest are 8 pin miniatures.

Regarding veneering: Over Xmas I had my first ever go. After experiments I settled on the apply PVA to both surfaces, then iron after ~45 mins method. Came out pretty well for a first attempt. Used a flush router bit to trim the edges. Picture attached.
