There is a vintage scanners yahoo group. Give it a try. If it a TME 8 they made a low band. They made a hi band. They made a Hi/Lo band and they made a Low/hi/uhf with 2 antennas.
its the same one i picked up at a garage sale last summer i looked around on the net and did not find a manual for it the only think i found was a sams photo fact for it and the 16 channel black version.
