I picked up this Crosman model 105 a while back on Gunbroker. It’s missing the grips as well as a few small parts but is otherwise in good condition. The 105 is the .177 cal model, the 106 is the .22 cal. model of this pneumatic pistol. There’s a general post about the 105/106 on the Pyramyd Air blog.
The odd thing is that the pistol has no markings at all. I’m wondering if it’s a particularly early model or if it’s what we now call a “second”.
Of course I love the loop pump lever. These are often found in a deformed state and later models changed the design so that the smaller open section is closed.
No markings…
Let’s get started/ One screw.
It looks like it’s not original?
The other screw wouldn’t unscrew.
So I removed the barrel band/front sight.
The dowel pin keeps it aligned, which is a nice feature.
Ahh, it’s not a screw, but a screw headed pin.
Removed.
Then it’s a matter of removing the front pivot plug.
A simple milled piece.
And the piston assembly is pulled out.
Linkage pin removed.
There’s a setscrew which locks the piston adjustment.
Pump cup assembly removed.
I used a Taig 3 jaw chuck with soft jaws to get a grip on the pump cup assembly and unscrewed it.
Fairly typical period pump assembly parts. More to come…
