Question Goulds mudsucker diaphram source needed

My engine club has a Goulds mudsucker that was salvaged from a zinc mine in franklin NJ. It was brought up by scuba divers from the floodd mine in the 1960s. Now, after over 100 years, the rubber diaphran is finally splitting, and needs to be replaced. does anyone have a source for these? A local Goulds dealer states he no longer deals with these pumps, only domestic water parts. We really need to replace it, as the pump is a local peice of history, and we hate to think of just putting it in a corner to look at.
I believe the diaphram is about 14" in diameter, and is about 1/2" thick

Thanks for any help.

I purchased a diaphragm from Graingers a few years ago that was about that size, I've seen several pumps that were similar that all used that same diaphragm, not sure if it would fit your pump.

Just looked up my old thread on that pump, seems I never took any pics of it. Grainger still sells the pumps, does it look anything like this$smthumb$

I've seen gasoline powered versions and dual diaphragm versions, some fairly old.
