Belated Xmas Gift - Raytheon Porthole M1101

[Eric H]

This is really odd, I have a Truetone branded set with a similar chassis, not exact but close, particularly on top, the actual tuner part is even identical but on the Truetone it uses a simple ramp system to move the slugs up and down in a smooth continuous motion, it's as easy as tuning a radio.

The tuner you have is rather difficult to turn and is usually in a set with a large X shaped channel selector knob (example: 10DX4), I would imagine it's a little difficult to turn with that relatively small and smooth knob?

Here's my chassis, some similarity underneath but the top side is much more similar.

Perhaps Rube Goldberg worked at Raytheon for a time?
