I have a Raleigh Equipe which i am in the process of refurbing and my frame looks a pretty similar size to yours... its a large frame but at 6ft 2 its a perfect size for me even with the saddle up.Prob a bit big for someone 5ft 10 but see how it rides and if its comfortable and not pulling on the back of your thighs then whos to say you cant ride it! Looks in great condition... bargain at £50.
