I checked the mid-ship pump for markings. I could find no mfg name/plate on the pump. The only thing I could find was the following casting number (which is cast on each of the pump end plates:
2002-H A 8 B (or 2003-H A & B)
The casting numbers look to be of the same font/style as the casting numbers on the front mount Barton pump so it might be that this gear pump is a Barton pump also.
