Bill,
Most accurate way is to look at the solder connections on C106, the three section electrolytic "can" behind the meter. If the connections and solder joints look like factory perfection, then you may reasonably believe it's an original. NO ONE I've met outside the plant can solder a joint that good and clean! If it is original, grab a small mirror and look for the date code along the side of that cap. For example, 0466 [or 6604] could be April, 1966, or the 4th week in '66. All originally install dated parts, such as tubes, crystals, etc., would have the same xx66 dating. Other indicators would be the service bulletin history. For example, SB-8A, but not 8B or 8C would also put it around 1966. But again, that's relative to whether they are factory installed. A keen eye will tell. According to Bill Harrison (of Harrison Radio fame), component dates average between three to five months prior to production. That should put you in the ball park.
Stu, k2qde
