Alternative to Pomona 2798

I’ve got a customer who needs to find an alternative for the Pomona 2798 BNC to PJ051/WE 310 phone plug as they’ve been discontinued.

I would assume this is something that should have equivalents from various manufacturers.

The 1297 may work if lack of the floating ring isn’t an issue. Apart from that, making one’s own with the appropriate connectors, some cable, and heat shrink may be an alternative.
