I have a question about a Kasuga, Tokyo SxS I picked up a few years ago. I can't find much information about the maker or the proof marks. It appears to be a quality built shotgun.

12 Gauge
Chokes IC and Mod
Weight Six pounds, 8 ounces
27" Barrels
Pistol Grip
3" Chamber by measurement
Manual Safety
No butt plate
Hand engraved with setter on one side and pheasants on the other.
1/2" Sling swivels

The water table is marked "STEEL" and "STEEL", one for each barrel.
The underside of the barrels are marked "STEEL" and "CHOKE" one for each barrel.

Do these proof marks indicate the shotgun can safely handle steel shot?

Ken I'll leave you with this. That's a really nice shotgun, you asked about steel shot and I maintain that you'd likely be OK, chokes etc. That said if it were mine I'd not do that. Barrels on that gun are irreplaceable. No barrels, no gun. I have no idea what you have in it and it doesn't matter, a box of TM or bismuth would be much less!

I know nothing about the proof marks, that said I think you'd be OK if the chokes are no tighter than mod. The chokes are not marked, at least not obviously, so a measurement to find the constriction. With the 3" chamber it seems that the gun was made with steel in mind, especially in a 6.5 # gun.
