Nice find. The last one of those Mk.I or "trials" foresight protectors that showed up on eBay sold for more than this rifle cost you, perhaps by several times.
We've seen a number of these early Maltbys with Beech Mk.I forends like this; had one myself. Very likely original.
Sadly Maltby stopping marking their production that clearly: purportedly for reasons of security.
I'm not sure how the serial numbers went but mine was A11816, and had that same Mk.I cocking piece, though the foresight protector was gone when I got it.
If you can take a clearer photo of the markings on the foresight protector we will be able to see if it is an RSAF Enfield made piece or not.
