APP. No. OPMI1A or OPML1A?

To my understanding of valve-related acronyms, it's an Output tranny with optional muffler?

Type: OX170 O = Output, x = transformer...

I've searched everywhere, nothin, zilch, cods wallop.

The grade of wires on both primary and secondary are the sort found on OPT, not the "stiff" like wire on the primary of power trannys that i've seen here often...

6 on one side 5 on the other.

The same goes for this second one:

Ferguson "OP6M"
6 wires on one side, 8 wires on the other...

Cheers! Any help would be greatly! appreciated!
