the redesignation to rifle number 3 occured in 1926 ,
the bolt lug revision was around december 1916 well before the wheedon rehabs but that is when the mkI* designation occured , the designation will be a star[*] on the reciever ring , top of the bolt handle , extractor , and on the buttstock right and above the manufacrturers rondel which is a stamp in the stock - not the brass unit marking disc , the rondel is larger on the remingtons than on the eddystone and winchester
the wheedon work was done in 1939 at RSAF-enfeild as well as a few private firms as the rifles were removed from stores and returned to service , they were cleaned , the dial sight pointer removed and the rear sight arm was cut removing the iris , at this time some were restocked with scotish made stocks[without volleys] and redesignated mkII
the wheedon marking is located on the bottom of the pistol grip and includes a letter designation for the location the work was perfofmed
the brass disc was discontinued in the 30s and it was removed and pluged as rifles were reconditioned and the fatso stock was the eddystone stock , the remington and winchesters are trimmer just ahead of the magazine
