Conn 12J valve diameter and bore size?

[cheburashka]

I'm watching a 12J on Ebay that's missing a lot of its valve hardware. I have a set of orphaned Conn valves with all associated hardware that are 1.065 in diameter with ports that measure .718, which appears to be a Conn #10 bore. Conn Loyalist doesn't list bore sizes for the newer Bb 12J. I was hoping someone could measure the casings on a 12J and give me an idea as to whether this would be a possible match to the valves I have.

Thanks
