Inches wide by have fun. The model numbers are for 1 khz, 2 and 4 khz ones. 35 thick, with pins distance 1.
These are all 455 khz frequency and symmetrical am filters. Note: I have been asked about the mechanical outline: measured this and found unit is approx.
These are all new old stock from Watkins Johnson and were used in receivers like the wk-87 etc. Appears to be Collins type LP. 7 inches, pin DOA. These are the new flat torsional type mechanical filters not old disk wire loaf of bread made by Rockwell-Collins, same great specs, more modern design.
