Chris Batha owns the Boswell name. His records go back to around about sn 12000.
Chris responds to enquires.
I have a matched pair of side lever BLEs. Chris has provided the provenance.
I'll be in Raleigh to visit my sister in a couple of weeks.
The Old Dominion Vintage Gunners are having a shoot NE of Raleigh at Rose Hill June 11th. The Carolina Vintagers are invited to join. (They want someone to beat.)
I'll be there. I can bring my Boswell pair. Let me know.

All Best,
Joe in Charlotte.
