Can anyone identify what brand of valve this is?

I was lapping my valves and noticed a nick in 1 of my exhaust valves (and I found its mate also, with a small nick too) right on the sealing line (face) of the valve so I need to replace those and want identical valves if possible.
Thanks for your time! The only marks are a DM on the valve stem up by the keeper groove. I am going to pull the intake valves and re-examine them also. They all held a good seal but I won't use a compromised valve.

Thanks. I needed to get this to as many people as I could. No replies so I ordered a complete new set.
Problem solved.

I pitched this thread in the trash but wanted all to know, that on a search and a hunch, I went out and bought a whole new set of exhaust valves, to make sure everything matched and when they came in, they did.
They appear to be BC3101 Exhaust Valves for anyone interested. They are physically the same and they all weigh 50.1- 50.3 gms.
Here are a few pics. They lapped in GREAT too. Now on to the head build!
The 3rd pic has 4 new and 4 used valves in the exhaust side, BTW.
