+1 on what Atomsplitter said.
The frame looks stock so at least it isn't a hard tail. It appears that the rake was achieved by a lower tripple tree extender, and not chopping the frame which was very common along with removing the swing arm.
The wheels are stock but they will have to be disassembled to paint the hubs. The the engine will also have to be disassembled to get at the crank sludge tube to clean it. These are a ticking time bomb if not cleaned because when these engines sit for prolonged periods, the crud in the tube hardens and cuts off oil supply. Come to think of it, Triumph may have eliminated the sludge tube because the oil in the frame models had oil filters. I'd still take it down though. Another plus is that the instruments are there and can be rebuilt if faulty. The right side cover is gone so the left is probably absent too. The good news is that these are available used on ebay and various vintage Brit bike forums
And that's just a start.
