P.O. Ackley 4x40 Scope

[Sunray]

Supposedly made around 1955. In Japan. Japanese QC was not great until their businessmen got rich enough to come to North America. Rumour has it that they were astounded at the much higher quality of stuff being made States vs what they were told to make.
It got a 7/8" tube with external adjustments? Apparently, Ackley did design and manufacture a scope and mount in 1955. If it's one of those, it's a collector piece worth $300ish. $150 for the mounts alone. Otherwise, it's a marketing thing that just has Ackley's name on it. All that is according to a guy on 24 Hour Campfire back in 2011.
Might be worth $25 just in case it is worth a pile of money.
