Only it's not a 797, It's a geardrive and has
the older fuel tank top. Could be an 840, 890
I would like to know the numbers on the block.

Yep. My guess is 840 or 890. The AF cover has a slotted head screw rather than a knob too. My guess is that cover is from a 1-75 or 1-76. I suppose the saw could be a 1-85 then as well. I can't tell from the pics if it has an auto oiler or not. No AO would make it a 1-85 methinks.
