Meyer E47 - E57 Pump units (Omer)

Looking to buy Meyer E47 and E57 pump units.
Prefer working units but may consider units that are not working.
State what unit you have, its condition, how much you are asking for it and where you are located.
Pictures would be very helpful.
If not a running unit, could you please indicate what is wrong with it.
I will respond whether I am or am not interested.
Paying cash.
If advertised as a running unit would be nice if I could see it run prior to purchase,
