Does anyone recognize these throat adapters? They are a rough approximation of a 2328. 2 inch, 4 bolt on one end and 3-1/4 x 1-7/16 on the rectangular end. The inside group of holes on the rectangular end also match up to the 2328.
I haven’t had a chance to clean them up and give em a try yet.

Apparently they were mounted to 2356 horns.
