They are worth some, but not a ton. I have one 2 man (Mine has coarser teeth) and two of the one man saws; they are actually not bad. We used my two man up in the mountains to cut slabs off a big (Over 3') fallen cedar log and then split that with an ax (didn't have a maul with us) and we were surprised how fast it really cut. The log was way too big for the small chain saws we had.
All 3 of mine are now on "display" on the inside of my (slab) garage door.
If you want to build some upper body strength, put those to use!
Those are both crosscut saws, named for their purpose, which is to cut cross-grain, as in felling or bucking timber.
Here is one of the world's biggest crosscut saws, used to fell a monster in Cathedral Grove, BC
No.1 looks like a seriously mucked up bucking saw, I would really need to see the teeth closeup to tell for sure, but the lack of belly and with the tooth configuration it seems likely someone who didn't know better butchered it.
No.2 is more interesting due to its length and tooth configuration( starter teeth?). I would be looking hard for a makers etch as it could be valuable to the right collector.
Ebay probably best source of value.....see plenty in the $100.00 range. They make cool wall hangers and no one throws them away so....probably plenty on the market.
