Interesting pics.. thanks for posting them...
It appears to me to just be a seriously bubba'd No.4 Mk1*, but perhaps I'm misunderstanding the point of the thread.
Why are the serial numbers filed down on the tang and bolt, then replaced? I assume it means it was a conversion from a previously serial numbered No.4 Mk1*?
Kind of reminds me of the lunchbox specials, salesman's prototypes examples of No.4's that surface from time to time. Is there any provenance or LB historical records on this piece?
I can't find any reference to an official Long Branch No.5 Mk1 Jungle Carbine, or any No.4 Mk1* marked variant ever being produced, although I can find a reference to an experimental one being produced using a 1943 No.4 Mk1* receiver.
According to Skennerton's newest publication
The Lee Enfield on page 319 ..
"At least one prototype .303 N0.5 jungle carbine was produced at the Long Branch factory, the illustrated speciman is from the Candian War Museum collection. This example utilised a 1943 vintage No.4 Mk11* receiver with No.5 type barrel, flash eliminator assembly and fore-end. The backsight is s No.4 Mk3, re-graduated to 800 yards, which makes it similar to the British-made No.5 Mk2 sight. The carbine is stocked to within 6.25 in. of the flash hider, similar to the ROF Fazakerley and BSA Shirley-produced No.5 model."
The photograph from Skennerton's book referenced above also appears on page 319 and shows it marked as a 1943 No.4 Mk1*.
I'd like to post the pics for Skennerton, Payne and Laidler to comment on, if that's ok?
It might be turn out to be a new chapter in everyone's Lee Enfield collector books ..

Doug
