6 Groove barrels on Late Production Smith Corona M1903A3

[Bearcat132]

I made a mistake and initially posted this thread in the Lee Enfield Knowledge section anyway here it is in the correct forum.

I have always read from the experts that the Smith Coronas had 6 groove barrels in the very first months of production and only 5000 or so. Now there is a seller claiming to have a 6 groove barreled Smith Corona for sale with a serial number 4800817 with a SC 10-43 date on the barrel. Still in the surplus box and paper from when it was purchased from the NRA and shipped from Raritan Arsenal in 1961. It has only the original cartouches and no arsenal refurb marks on the stock . As for the 6 groove barrel I thought this was not possible according to the experts. I have asked the seller to provide a bore picture to confirm this claim, but the funny thing is I own one with the same story but different shipping year that is only 34 serial numbers from the one he has for sale and I thought I counted 6 grooves in my SC 10-43 barrel which I initially dismissed I will post the link below. Either he is wrong or there were more 6 groove barrels floating around. I want to hear from the experts on this because if it is true it will add another footnote to the Smith Corona M1903A3 lore.
