Trolley Jack Identity

[Sonic70]

Hi All,

I just bought this sealey jack second hand. Can anyone identify it? The label is quite worn, at a guess it may say 1250CX but i'm not 100 per cent sure.
Also I have set the oil level 5mm below the filler hole but am not sure if this is correct either.

All help appreciated.

Yes it does have yankee on it. What is difference between mk1 and mk2?
