One is a casting from a Ruger Blackhawk,,,
The other is from a Colt Cobra,,,
They are cast with aluminum.
This is a closeup of the metal,,,
It can be sanded and polished to look much better.
I wish I had a pic of the one I painted,,,
After some sanding and using dark blue automotive paint,,,
It looked good enough to display in a custom gunslinger rig I once made.
Anyways, the contact info for these dummy pistols is in post #10,,,
The last time I ordered one they were $45.00 each.
I hope this helps you.
