Collins 312B-4 Round Emblem Station Console in Excellent Condition LATE S/N 72709

This Collins 312B-4 Round Emblem Station Console in Excellent, Condition. It is a Late Serial # 72709.

It has the correct ABS trim ring, and original feet & Risers. The Trim Ring has been epoxy painted so it will never get Yellow from UV as most of them do. The color and finish matches the original Collins Trim Ring.

The front panel and cabinet are in beautiful condition with no bad marks or scratches. This 312B-4 is in exceptionally, Nice condition! The Paint and Finish are original.

I also checked the watt meter functions. Everything looks to be okay and the wattmeter is within spec. I did not check the phone patch or other switch functions but everything appears to be in good working order. The Speaker is also in nice shape sounds great. 

I will supply a copy of the instruction Manual with this item.
