RCA 630TS which one came first? some minor variations

[M3-SRT8]

I saw this old post, and had to reply, belatedly.

I have two 630TS's, one an early (junker) chassis without the keyed AGC, and another, slightly later complete Television Set with a Keyed AGC Adjustment, factory installed, with the single large Brass Clip on the front glass. They Keyed AGC does NOT have "AGC" stamped in the metal chassis.

The Serial Numbers, Production Sticker is missing from both sets. Is there another way to find out when they were built? I can't see any other stamps on the Chassis, like a production date, to indicate when they were assembled.

By the by, I just finished recapping the chassis, checking/replacing resistors, etc. Also, the chassis got a complete cleanup and a partial cosmetic touch up. The Cabinet I restored from the Ground Up. It needed it, and it looks great, right down to the (redone) factory grease pencil marks and repro'd labels. It looks like it just rolled off the Assembly Line.

Now, for the Final Phase! Alignment, Voltage Checks, etc.
