He posted this on the airgunforums.co.uk site but hopefully the discount applies to gallery members too!

High quality 3D printed scope mount for the classic BSA Standard No2 air rifle.
This scope mount is made from PETG, a very strong and durable plastic. It has an 11m dovetail rail that is 120mm long and allows the fitment of a scope or other optics.
The mount has sympathetic styling and is 100% removable as no permanent alteration to the air rifle is required. It is designed to clamp onto the 31.8mm main cylinder and is held securely in place using 2 x M3 bolts and captive nuts.
To install the scope mount, remove the trigger block and slide the mount over the main cylinder. Replace the trigger block and slide the scope mount all the way back until it butts up against the trigger block. Align the scope mount so the top rail is square to the barrel and tighten the 2 M3 bolts.
Ed cautions:
Someone asked if they would fit a Light pattern, well the answer is no because of the cocking slot distance.
Although all pre-war BSA (except the Juvenile model) share the same air cylinder dia, the cylinders are different lengths and the relationship between the cocking slot / rear block varies....
The cocking slot end to breech block distance on these (Improved Model D .22) is 50mm, add the cocking lever pulled back overhang and it's more like 48/49, so the mount needed a gribble at the front to get the full cocking stroke on the IMD as per phot, maybe 2mm clearance as the cocking arms are cast so may vary a tiny bit I suppose.
Was not sure how tight it would take, so nipped up the two clamp screws quite tight and even, and used a torque drive to mount the scope, seemed happy to take 3nm with no issues with the dovetail rail, and all feels firm on the gun.

As I had sold up I bought a cheapo Nikko to start, have a bugbuster I can use off my 80, but wanted to get some lead flying.
Quick zero and 50 shots later (gun does mid 11's so up there power wise) and rock solid so far, shot into a book from inside just resting on a chair back and although I knew the gun is a good un' I rattled off an effortless one holer at 12 yards (most I can do here) so will be interesting to see what happens when I can get to the warehouse and 40 yards plus.
