Need help identifying IC's

[LEON.01]

Got a load of really old electronics gear from my uncle.
I found these IC's which i haven't been able to identify. Cant find them on the net anywhere!!! 
He only played with sound circuits so i think they would have some use in a pedal/amp maybe!

They seem to be of some kind of metal, They have the code TRI-SAGE MC 1127 on the back, also a number which has been scratched off. i have 8 of these and they are all the same.



Anyone know?

Not really ICs but more of an encapsulated circuit.  Similar to the ones found in Mosrite Fuzzrites and Rosac effects.
