Picked this up at an old farmstead a while back and trying to ID. When I got the pump I was thinking it was a Wayne 851 but after looking at other 851’s it seems to have some differences that now make me wonder (unless there were different versions of Wayne 851 pumps?)
Any ideas?
Thanks!

Picked up the rest of this pump over the weekend. Looks like I’ll be trying to find a light manifold and clock mechanism.
