Hi, I made a reference to a valuation on one a few days ago
A member mentioned they easily go over our limit, On a Google I found this .

I have had a few of these, They have a smaller diameter pump tube than the Sharps hence the number of pumps goes up but easier pumping,
Mine is tired & Requires an inlet valve seal but still makes good power,
+ Points- Will last forever, Easy to work on , Hold their value ,
