I received a Collins Mechanical Resonator in a box of goodies I purchased. It looks like a Collins Mechanical Filter. Model 1045 AA Frequency 1045. It has 5 pins on the bottom, 2 on one end and 3 on the other. Any one have any experience with these. Oh it's about 3.5 inches long and about 1" X 1" high and wide.

Thanks in advance.

I may be a selective tone filter. I have a load of stuff with Collins filters on the cards
post a pic of yours , and i'll grab one to photograph next time I am where the cards are.

Most modern Collins parts have a part number that is like, XXX-XXXX-XXX on them. 3X4X3 format.

Part number is 526 8026 00

Serial number 119 P

I am not intelligent enough to post a picture here. I have tried and I think my pictures are too large.

I will try again using my cell phone camera.

Still too big.

Hey! It took me weeks to figure out how to post pictures.


I would imagine a ten-year could have done it in 30 seconds. But, you see, I would be
clever enough to get them to do it, and then thank me for letting them show me.

That part # doesnt show up on any of the Collins filter lists so it must be a special.
