It has the 3 speed hand shift, I am guessing early 50's??
I don't know. The ad says it is a "Goldfinch" but I don't know the MG lineup enough to really know more than that.
Any motorbike can be restored , it comes down to skill and money . The less skill you have , the more money it will cost . There is a a group of guys who do a tour around Arkansas and Missouri every year on motorbikes that are on the road for $1,000. or less . Mostly older Japanese bikes built in the 1970's . Of course building a reliable runner on that budget isn't much of a problem if you already have spent several thousand dollars on similar models to steal parts from , and have a shop equipped with a lot of expensive tools .
