Sounds like the decommissioned rifles are headed to Ishapor to be made in to .410 single shots and then reissued there for guard duty.

That'll make lots of SMLE followers cry here in the USA who dreamed of another supply of surplus SMLE's coming to the States like the great 1990's group from Australia/John Jovino import.

None that are viewable in the pics above seem to have the normal 'Ishapor Screw' laterally through the forestock. That would give some indication that they are English made rifles or very early Ishapor built and have never been back for repair after India Independence when that reinforcement feature was made popular.
No square eared nose cap wings either common of the later India mfg rifles.

I've still got 3 that are 'orig' features.
BSA 1906 MkI* SMLE that took some time to put back to orig shape with some parts from another.
BSA 'Commercial' MkI* SMLE could have been made as late as 1914 I'm guessing
BSA 'Commercial' CLLE Long Lee, "" ""
A couple SMLE bayonets and at least one for the LongLee.

Recent purchase of a sportered .22MkIV.
Excellent bore. Made up on a WW1 Enfield mfg SMLE ('M' ser# prefix) in 1954 & FTR.
Someone then cut the forestock and removed the handguards.
I have handguards front and rear for it. I'll make the missing forestorck wood and splice it in under the front band (also missing). Front band and nose cap, screws, ect are parts I have so it will be back in shape at some point.

Same old story of MilSurp rifles.
They get bought cheap at one time,,cut up and sporterized,,then later on we try and put them back together again like a HumptyDumpty when the prices go up as the supply dries up.
