Default Throatless shear

I have 2 Marshalltown throatless shears. Neither have any identifying labels. I've been guessing there are the 114. The cutter wheels are 3 5/8". I'd like to buy a spare set of wheels and a spare lower shaft. Any ideas where I might look for these?

Also, I'd like to buy a 3rd machine. I found a Lennox 18. Is that a comparable machine, or is it smaller?

I just went through line boring my marshal town throat less shear , making new axle and cutters . You could wiggle my upper axle 1/16" it had 1/32" of wear on it the rest in the Babbitt .
My axle had 4 key ways cut in it and the taper fit poorly one of my cutters chipped much like flint would flaked a shallow pcs of all the way to the key way . Looked to me to be to hard , so I made new wheels from D2 and hardened I think to 58-60 rc . Cutting the serrations was a beech single pointed them . It was killa hours of work but love it . My cutters 4 1/2"? it's axle 1 13/16" ? if I remember correctly . Mine came with 4 speed gear motor and belt drive The mounting was funky so I remounted it and used a ring gear from car and a pinion gear to match the pitch .It also has hand wheel I put in netral and it is amazing how easily it cuts it's rated 10 gauge steel by hand

I bought another Marshalltown Throatless shear. Found it on Craigslist by accident. I bought it sight-unseen. I thought I had the large version. This thing is a monster compared to what I already have. It's still laying on the pallet it arrived on. I have to fabricate a stand so I can try it out.

In case anyone is interested, May Tool did a nice job of sharpening the blades off of one of my other machines.
