An interesting old Coil

Millgate might be the Chorlton Metal Co ?

What amazes me when looking at old magazines from the 30s is just how costly everything was by today’s standards. For example, in the text at the above link there's reference to a Millgate 120V HT batters at 11 shillings (55p), which the text says represents 'very good value for money' as it may well have been by the standards of the day, but when adjusted for inflation equates to £34.50p. Heck, you can buy a DAB radio for much less than that now.

I don't know how long a radio would have run for on an HT battery, but I can well imagine that radios weren't just turned on and left on for hours on end,but that people had an eye to running costs. This was, after all, during the 'depression' era.

When you look at those coils, and how much time and effort went into designing and producing them, it's clear that they were quality items requiring a lot of labour to assemble them. I dare say too, that the production costs of the Bakelite formers were high - tooling etc. Most of the firms who produced this stuff seem to have been small outfits who wouldn't get the benefits of economies of scale.
