Perreaux TU2

I needed a fm tuner and purchased a brand that I am unfamiliar with. I bought a used Perreaux TU2 fm tuner. It is a rack mount that has a very simple layout (digit display for freq and a freq adjustment knob) Does anybody know anything about this tuner? I know it is old but is it any good? Any idea on the value of it?

Thanks for any info.

No joke Gary: older the better when talking tuner;there is only few exceptions at crazy price. Are you sure TU2 is old?
All my tuners are really older: Sansui 777,999 Sony 5000FW,5130,5150, HK 1000 and few others.
