Check the listing for details. Collins Mechanical Filter 500 KHz CF, 3.8 KHz BW LSB 526-8444-010. Condition: Open box. Listed at 50.00 USD. I found another stash of these: Collins "Loaf of Bread" style mechanical filter, type 526-8444-010, USB, 500 KHz C.F., 3.8 KHz BW (shifted down from CF), input output load 2K ohms & 20 pF. I also have the matching delay equalizer 524-5001-040 if you want it (you have to request it). These are new old stock, roughly 1/2 x 1/2 x 2 5/8 inches, 2 threaded studs on bottom & 4 wire pins. I have the matching LSB filters as well, so you can buy a pair LSB/USB!
