Here's a couple of pics kindly sent to me by Martin of his father's "basket case" Lincoln "H" air rifle, which has now been restored to working order.
It's a 'long tang' trigger guard 3rd batch Lincoln, serial no. 5079, made between January and March 1906 according to Mr Knibbs. Interestingly, the stock has the usual LJ 'shooting man' etc markings plus there is an oval plate inscribed with "J Venables Son, Gunmakers, Oxford" "
Martin's dad found it in a barn 10 years ago and paid £5 for it. The rifle was full of cobwebs and was badly rusted, with the stock split around the pistol grip. The loading tap was heavily rusted.
It had no rear sight, a missing bead on the front sight, and the the lever catch and a butt plate screw were also missing.
Here are the pics of the rifle in the condition it was found in:
