Can you tell me if this strop is any good?

There's a little dry paste on one side. Looks hardly used, what would I need to bring it back into service?

Hard to say. Top half of the strop seems nick free so I would give it some neatsfoot oil or any other leather conditioner and give it a go. It won't destroy your razor.
