From what little is known about the box, it should be about 23 x 14 x 3.5 cm in size and covered in dark blue crocodile-skin type paper. If you had the lid, there should be label stuck inside with the name Titan and a picture of the gun.
It would be shame to leave it in this condition, but as there's no way you will get spares, it would need to be restored by someone both with restoration experience and a complete original to copy from. It looks as though it will need a trigger, trigger guard and cocking rod. As far as the innards go, there should be the mainspring, a small piston and a safety catch in the grip. Good luck with it!
