An old 3/4" flanged tap connector is near that.
I have one here. Measurements are.

Bore = 17mm. (5/8" = 15.875mm)

O/D = 20mm. (3/4" = 19mm)

The flange (which I can't quite get at) looks to
be about 23mm OD, and there is plenty of length.

That 20mm OD is the bummer.

Nothing a smart tap with a big hammer wont fix.

I was wondering about tap connectors..
