Interesting Customized Hy-Score Pistol

[45flint]

As a vintage Airgun collector I always go for perfect all original guns. When I saw this however I had to have it. The Hy-Score as much as I like it was still made as a economical pistol with many features not quite up to firearm standards, of say the Haenel 28 or the Webleys. However someone customized this pistol and tried their best to upgrade everything. The most obvious is the walnut hand checkered grip. It is perfectly milled as precisely as a factory would do it or even better. He must have milled a new trigger guard to intigrate the grip and got rid of the one that was sheet metal. Though difficult to see in the photos he even had to mill into the trigger guard a keeper for the trigger spring. The back sight on a Hy-Score is really poor, he changed it to a milled one with a milled height adjuster. I assume this was a gunsmith with considerable skill. Don’t know if he was repairing a old Hy-Score or just upgrading it. Looks to have been done many years ago. Interesting question is why would someone spend so much time and effort on a relatively inexpensive air pistol?

Interesting.

Have you shot it? Looks to me like the rear sight is set far too high for the front blade. Might hit around point of aim at about 50 yards?

No haven’t shot at a target, just oiling it and shooting at a Chrony to get it back in shape. Not sure you are correct it you look at the last pic comparing this with one I have sighted in. Looks about the same? Also the gun has a milled riser where I can adjust, it in the middle right now. These guns have a rearward moving piston. This causes the barrel to dip and they have to sight these high to compensate, per Andrew Lawrence’s paper he wrote on making this pistol. Test the theory when I get a warm day.

I was thinking the same. Just looks a bit too much to my eyes. Probably wrong. For that exact reason. Enjoy, nice score (no pun intended).

Now that's a nice looking and executed custom job, I think your evaluation is spot on with the upgrading.

As to 'why' well we can only speculate,but many a Webley have had the sights and grips changed by enthusiastic owners over the years, as have Crosman gas pistols.

A nice find - well done

Very good point, over here there is a cottage industry making custom parts for Crosman CO2 pistols. Webley wood grip upgrades are pretty common as well. This is the first I have seen on a Hy-score, not surprising given the grips are so integrated to the pistol.
