Looking for old check valve 1

[CheckMate]

I am with a Forensic Engineering Firm. We are investigating a failed check valve. The one in question is a CheckMate CV-200 by Liberty Pumps. I need a similar valve to disassemble. This valve has a yellow sticker and is round with a glued together body. Does anyone have one in stock or know where one is installed. If it is currently installed, arrangements can be made for replacement with a newer model.

Good luck

I am in contact with Liberty Pumps regarding the valve. They changed the design in 2001 which is bolted together not glued. The new valve has a large and small washer attached to the internal flapper.
I need an old valve which has the glued body. The one I have is missing the internal washers, but they are probably both smaller in size than the newer unit.
