In my opinion there is no way to fairly assess the value of a pump from just pictures alone. Also since there seems to be restoration work done the true value can't be assessed without knowing the quality of work.
Therefore I think it would be only fair to assess the value as a pump found in original condition.
The Wayne and Tokheim visibles sell in the $1800 range unrestored with good cylinders.
The Wayne 100 electric pump sells unrestored for around $800. Yours has been modified with a showcase added which is not original.
This should give you a starting point.
