As long as we are following strict S&W protocol, grips are stocks - checkering is checking - crane is yoke.
Unfortunately, over the years, as ownership or management came and went, some of the "other" terms crept into S&W literature.
As far as stock medallions or monograms is concerned, The D-2 catalog from January 1921 states,
Monograms
We have discontinued the policy of placing the gold S&W Monograms in the Wood Stocks and hereafter all of our arms will be marked with the S&W Monogram on the frame as we feel this to be a far better place for this identifying Trade Mark.
It cannot easily be removed from the frame, which is the case when Stocks are changed, and then again in omitting the Monograms from the Wood Stocks it enables us to build them much fuller at this point, thereby giving the User a better hand hold."
And just to confuse things a little, "Cokes" were not all checked, some came smooth, so the amount of checking cannot always be used as the identifying factor. The main thing to look for is the flared bottom that sweeps inward as you move upward and then the curve back out and in again. Think of the shape of the old glass coke bottles and you will be able to differentiate them.
