Hi Gary , BCC Calliste 072 , 1985 has bronze ports that have no markings on them , so I don't know if they are ABI or not.
The glass in Calliste's ports are 7 5/8" diameter plus or minus.
There is a large threaded ring that screws down onto the glass.
There are two annular groves machined into the spiggot part, and these are used for two ss wire rings one on the outside of the screen disc, one on the inside.
The adjustable hinge looks similar to Dan's photo, but there seems to be a little difference in the dog down forks,,, and there are "bail" nuts instead of wing nuts.
Mike Anderson showed me the best seal,,,,, it comes from Perko, and has a "T" , shape.
Port Supply used to stock them, as 10' lengths, you cut to fit.
I had to rebed all the port glass, used silicone , have had No leaks,,, phew !
