Looking at your pictures it looks like you just need to change the trigger guard, not sure if it a made one, home workshop job.
There is a lot of confusion in this thread.
The cocking lever fits the action, so must be right.
Trigger blocks are interchangeable, so can be switched from one gun to another instantly.
Both the post WW1 .177 Light Pattern 39" and .22 Sporting Pattern 45", are both BSA STANDARD air rifles, so the use of the word standard is very confusing.
The rear tang on the trigger guard does not fit the cut out for it on the stock, so it is likely that the trigger guard is a replacement, and not a genuine article.
Whilst I have seen many Light Patterns with 141/2 inch stocks, I have also seen light patterns with 131/2 inch stocks, so both can be correct.
The S- prefix before the serial number denotes that the trigger block originally comes from a .22 Sporting Pattern, however will work perfectly well on a 0.177 Light Pattern.
Lakey
Possible a gun assembled from parts, and, as such I'd say £180 is too much.
The South of England has 2 good things, the M1 and the A1. Both will take you to Yorkshire.
I have taken more photos now. Please have a look at the way the foresight is positioned. The rifle shoots very accurate, but what the hell is with the foresight being to the side?
