[Collins] RF Choke ID

[bill riches]

I found a NOS Collins  Ceramic Plate RF choke that I am trying to identify:

 

Total Height 5 9/16

¾ diameter

1 7/16 x ½ mounting flange with 2  6-32 mounting holes drilled from the
bottom of the flange.

Coil wire has green insulation and measures 37.5 uH. The number 540-7979 was
written in pencil on the bottom.

 

Any info on this choke would be appreciated.

 

73,
