Very Heavy Duty Crane £200

Having a tidy up and not used this in years so time to move it on, there is no rating plate i can find, it lifted out my 19J with ease and i`ve used it to lift the front of my 90 up a meter high to get stands under so plenty of capacity. It does not fold up and is very heavy and seems to have a slight seep from the pump area but i have only topped it up twice in the years i`ve had it.
Looking for £250 I`m in Essex near to Lakeside shopping centre and QE2 bridge.
