The first one is a Super 44, 80 cc version of the early hot rod saws by McCulloch. The D-44 was 72 cc, Super 44 80 cc, and the Super 44A 87 cc. By the way, the Air Filter cover is on backwards.
The D44 had a stamped AF cover rather than the cast one like the Super and SA, the Super 44A normally had the "hockey mask" cover over the air intake on the flywheel cover.
The other saw is a peculiar adaptation of the venerable 33/35/39 series saws. To make a direct drive version they had to lay the power head down on its side and ended up with the bar on the left hand side to make it spin the right direction.
Here is a rough 35 A with a few broken/missing bits. There is a bevel gear box on the front of the saw and the bar is pitched up at an odd angle.
There were many different attachments available for these saws, spur reduction drives for auger bits, a direct drive drill with Jacobs chuck, ice auger/earth auger, brush cutter, and the bow bar.
