Pump Identification to find a Top - Primarily Petroliana Shop Talk

I would appreciate anyone's help in identifying this pump to try and find a top for it. It is a Bennett according to the meter that is installed on the bump. I thank you in advance for any help. Ron

Looks a lot like my Bennett 3115 pumps. Sorry, no extra tops. - Jack J.

Thank you JackJ. Very helpful, now I have a way to search for one.

How much of the top is needed?

Just the very top the sides are there. Thanks you for any help.
