I realise that it is only worth what you are prepared to pay for it, as applied to almost everything. In my experience when you want something the part is mind numbingly expensive and when you are trying to sell it, they are worth nowt! 
Anyhow, now that I have finished pontificating, I was asked what thia would be worth, it is a Centec horizontal mill. (I think!) Table size is about 18" long, and it is single phase. The person who has it would like to know what it would be worth?
and anything else you might be able to tell me about it.
Thanks in advance as always
