Scorpion pistol with stippled thumbrest

[evert]

Another Scorpion pistol turned up I bought it for parts, to complete a pistol in my collection with a modified frame...
But when the pistol arrives, I find that the tumbrest is stippled, something I have never seen on my other Scorpions.
It seems like the stippling is original with the casting of the plastic frame, and not a modification.

The gun is a .177" with a PA serial nu,ber prefix, and has scope grooves plus the later "kemetal" plastic sights.

Does anyone know anything about this thumbrest stippling? Does it tell us anything about when the gun was made?

I had one like that too.... don't think I've still got it, but I thought it was nice.

Yep, they are quite nice guns
Checked my other Scorpions, and in all other details, it is identical to the other mk2 I have, except for the thumbrest stippling.
The serial number is a bit later than the other mk2, so it may have been a production change in the frames?

Venom tuned Scorpion.

I had no idea that was a thing.

Venom tuned Scorpion.

I had no idea that was a thing.

Apparently, Bowkett tuned them as well.
