Roth, it's pretty neat that you are sharing pages from the 1939 catalog since that is the year of manufacture of my 1903. That makes those pages especially 'collectible' to me.

I did note that they refer to an 18" bbl on the 6.5X54 stutzen yet my bbl is 17.7". Only a 1/4" difference and I think the post war carbines were 18". My shorter bbl was probably just another 'transitional' anomaly. Or, it could be that they were just rounding to the nearest inch of length.
