None of the Sandusky mfg 37's are available as a TD?
I don't know anything about them but assumed (bad thing to do) that they were a standard Ithaca TD system.
The early 37's didn't have interchangable bbls off the shelf (that came later in production), they had to be factory fitted. But they were still able to be taken down.
Yeah, I don't get it. I emailed them and they said there's chatter about making the 37s with a standard barrel, but that's all it is now.
