maybe the solution here is to line the chambers for 32 ga 2 3/4" shells, which would then require rework of the extractor...

The official nominal bore diameter under CIP for the 28 is 13.8mm and for the 32 is 12.7mm. It seems you have a tightly bored 28. I am assuming you measured bore diameter with a metric gauge.

The threads for the bushings are almost certainly metric.

If the gun was made in the 1970's it would have a 2 3/4 chamber. The gun is most likely a 28 bore with tight chokes and chambers. I have a 16 gauge Beretta hammer gun made in 1949 with tight chambers and chokes as well.
