Antique "arborist" tool

[Norwayclimber]

I was sorting through some old gear/junk when I found this antique "arborist" tool. Didn't quite know what it was, but after calling the former owner, he explained me he made it when he started felling trees in gardens. The item screws onto the top step of a ladder, so the ladder wont slip when "pruning" the tree. We both had a good laugh!

I have my grandpas old craftsman saw, its from the 50's and has a top handle,12" bar, just a little smaller than the 200t, trying to get it running so I can use it once in a tree, ya know, a little bonding with the old school!
I also have a bunch of the old big hand saws,6', old school is cool.

Would this still qualify as spikeless pruning?
