Detonics .45 ACP

[Crash]

I have "temporary possession" of a Detonics .45 ACP and need help in identifying the year of manufacture, value, etc. On the right side of the fame it's marked "DETONICS .45, SEATTLE, WA." The serial number is CR17037 and it has a 3 1/2" barrel and is satin nickel or stainless steel. Anybody know whether it's nickel or stainless steel, the approximate year of manufacture, and its approximate value (I would estimate the condition at about 90%)?

Thanks,

Crash
