Bayonet help for a Mk V

ill not argue anything about that transformation - i was not there - but we all know the no1 and no4 rifles are different even tho they may seem similar , i never owned an original no4 of the first generation [always wanted one] but even tho they are different in some ways they lost most everything of the no1 in the transition , they were a NEW rifle generation in the enfield line , the no1 died at the mkV , and yes i did own one of those in near original condition - considering that these got slapped together when issued mine was as originally designed , 

as to the bayonets of that post - they were the P07 , long after the hookie but still the P07 when designed , there were few being made in those years so they would have been WWI vintage by design , the indians manifestations were oriented around their use of the rifles and we all know they adapted to the 762 cartridge at that same time - long after the trials and long after the mkV was even considered a new development , by then the no4 was the NEW rifle 

This is just my opinion and an observation at the same time.

Leave the buttstock alone. Remove that marking disc and fill in the offending hole with a dark epoxy resin. You will still have an all original rifle and a story to tell about the buttstock in the coming years...
