[Milsurplus] ACL receiver question

[S. Schappert]

G'day to the list !

I am seeking any documentation or information on the following military
receiver:

Mfg:  Astro Communication Lab (ACL)
P/N:  SR-250
Description: Military dual VHF/UHF mechanically tuned receiver

Part of AN-WLR10() Counter Measures Receiver Set

Built for the Department of National Defense Canada

This receiver has dual pull-out tuners of varying freq ranges

I am looking for technical docs or information about the receiver or WLR10
systems.  Also if anyone knows of either companion SDU or plug in tuners for
this receiver I am very interested to hear from you.  There are outputs for
IF and SDU and am looking for those frequencies.

Thanks very much in advance for any help with docs or finding peripherals
for this receiver.

Best regards to all!
