I don't know if it's exactly the same but Larry S aka Chainsaw57 had a big old Disston at a couple of GTG's .That thing had about a 5-6 foot bar .

Looks like a couple of Disston/Mercury KB-7AY saws.  I have a 1947 KB-7AY (11HP).  Got a 72" bar for it.  They'll pull more.  3/4" chain.  15ci/245cc twin.  Powerhead is something like 70 pounds by itself.  Guys would run up to 10' bars on one powerhead.................and up to 15' bars with two powerheads....

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.
