If you can find that link again and let me know where it is we can likely fix those pictures
As far as the pump -
- CARburaTER cast - Red arrow
- button top,
- natural cast aluminum body,
- zinc dichromate stamped steel sections
- engineering number and date is stamped into the side of the mounting flange - Green arrow
Sure someone will come along and provide the correct engineering number for your application
If you find a used on they can be rebuilt and restored just find a good candidate (no pitting, hasn't been blasted...)
