I agree. Highest SN I've seen is 707134. Unadjusted vs adjusted is all over the place though:
694k Unadjusted,
699k low Unadjusted,
699k hi - 700k low Adjusted Temp.,
700k mid Unadj. Unadjusted,
700k hi Adjusted Temp.,
702k-706k Unadj., then
706k-707k Unadjusted.

Go figure. This lends credence to the idea of runs produced or imported out of order.

Now you know what's really fun: Gruen was still producing 117 (and 119?) calibers during the run of 123s (or even later!!). In particular, the caliber 117N was certainly made after 1930, and there are examples with Conoruma balance (post 1935).

119 - 641935 Un Adjusted, Wadsworth 5456463; 123/108.

117N - serials scattered in the 576-586k range; Un Adjusted, Wadsworth 545xxxx serials and cases 123/108 for the few that still have cases.

I think this would indicate that some plates were held back (QC?), and later, Gruen remanufactured dead stock. I'm not suggesting that the plates were still being produced.

I would love to get my hands on a Conoruma Quadron... !!
