I am about to send these barrels off to be opened a bit but got to thinking I may not be interpreting these marks correctly. They are on the 26" barrels of the B.C. Miroku 20ga I posted earlier.

Jerry,
I believe the Miroku choke marking would be consistant with the Browning ones, that would make it Modified. According to the Browning book by Schwing, the 20ga. should have a bore diameter of .611 and the Mod. choke would be .018.
Hope this helps.
Karl

Jerry,
Yes it would. I have several fixed choked Brownings marked with the same designation for a Modified choke. Improved Cylinder would be marked as xx-.

I read those as Mod and I/C. As the chokes become more open, the markings get "longer", so that a gun could be opened up, and the designation can be changed without altering the appearance of the gun. (I know what I'm trying to say, but am doing a poor job of describing it)

Jerry,
The Browning/Miroku choke designations would be as follows:

*** Cylinder
**$ Skeet
**- Improved Cylinder
** Modified
*- Improved Modified
* Full
The lower barrel would be Improved Cylinder marked on the right side,
while the upper barrel would be Modified marked on the left side.
Hope this helps,
Karl

Edit: I was wrong. I have assumed for the past 40 years that Miroku and Browning chokes were the same. Owned several and never knew any different. Good to know, I guess...

John,
I only saw one picture, showing the left side of the monoblock which I believed to be marked Mod.

Above the ++ marking there is a +- marking.
