They used to cost about $10,000!  It's a 1970's design but not a navigation 
receiver - it's a time transfer receiver designed to get time from Loran-C 
and output it on a data line.  Regrettably not much use now because it was 
set up for the old Loran repetition rates and they've all changed. It was a 
hardware set-up as far as I can remember so no chance of re-programming. I 
expect that's why it was junked.

Quite a few observatories used them - if you really want data you might try 
Uppsala Univ who were users in the 70's - or the Navy, for information. 
Austron themselves, a U.S. company, no longer exist.  Their main business 
was making very nice highly accurate reference oscillators - I have several 
of their 5 MHz double proportional oven units.  There may be one of them 
inside the unit - if so it'll be a grey metal sealed box, probably type 
1120, and very nice as a frequency reference.  I can send you full details 
if there is.

The 2082 was as you say a front-end set of reject notch filters to get rid 
of Decca and other LF interference.

Can't think of much use for them now. Even if you dug out the 100 kHz 
front-end you would probably have to change all the pot-cores to get it on 
136 to use as a pre-amplifier. As a pure Loran receiver it's useless.

Sorry about that!
