At first I thought this was a TR6 Trophy. But now see it is a 250. It's not a valuable nor a very desireable bike. There are people who are into them, as their are folks into 441 Victors. But there are also people who collect door knobs.
The suggestions given here are right on the money. Get the manuals for the bike, clean it up, inspect all the key bits and pieces and see if it will run before you worry about anything else. Even if you have to make a temporary direct wiring system between the battery, switch and the ignition system, which you probably will not have to do.
Then, if it runs and you really like it and plan to keep it forever as a family momento, spend what you want on it. But never expect to get your money back when you sell it. If you decide it's not the bike for you and nobody else in the family wants it, a running bike sells better than a non-running bike.
