Can anyone identify this tool manufacturer?

[DavidABQ]

I won this as a door prize a couple of years ago at the Colorado State SB Silhouette match and I would love to get more bits for this handle.

Does anyone recognize this handle or bit manufacturer? It is a well made product and I like it a lot and I was hoping someone could identify it an I could them get more tool bits.

The diameter on the tool bit is 0.375" or 3/8" of an inch if you prefer fractions ovr decimals.

Any ideas anyone?

Thank you very much.

At .357 it is to big for a primer pocket cleaner but that's what it looks like,,,,

The actually cutting bit is for a small primer pocket but the outside diameter of the tool bit insert is 0.375”

I think the name Markle is also connected to it. I have one, but I bought it many moons ago! I googled Markle reloading tools and got a hit right away.
