It is back together, I was able to accurately locate the dials by using my frequency counter to find the peak of when the capacitors were fully meshed, and used that for the end of the tuning scale / stop.
The bandswitch / tuning unit still has a problem, as the RF oscillator on one band does not run.
I am putting this in storage until fall / winter as I don't have time until then to work on it. The SP-10 cam fits perfectly, as do the slides.

It's the only Hammarlund besides my SP-10 that I have seen with a chromed chassis.(and the only one stamped with the tube numbers) The SP-10 looks so much like the Scott radios of their time, and about as complex mechanically.
