This depends like others have said on 1) condition that it is in now. 2) parts that are missing. 3) if the cylinders are there, and then if they are the correct triple etched ones and which color the glass is 4) location and travel time 5) does it have any globes with it and are they repro or original. This is why as stated the prices can vary by up to $5000-10,000 dollars. Big range and big pump, also if it is an early one or a later version. Just need pictures to help.
