New Garand Day!! 12-1941 - Lend lease?

[Tom Doniphon]

Did anyone else notice that the Lend Lease rifle for sale at Ohio Ord. has a grooved elevation knob instead of a checkered one? Several of the Lend Lease Garands in this serial number range have grooved elevation knobs. Now I know that some collectors believe the Lend Lease rifles were broken down for cleaning and the knobs replaced w/o regard to the type (grooved vs. checkered). But others believe that the use of the grooved elevation knob may have started earlier than had been thought. What do you guys think?

The straight knurled (grooved) begins to appear in the ~8 - 9-41 serial range but since a few books don't have them "carved in stone" that early, why dispute the written word? Perhaps some discrepancy occurs in the descriptions of "knurling" to the layman:

1. "Fine" checkered vs "coarse" checkered.

2. Straight grooved vs. straight knurl to me means the same thing. The machining principal is still the same whether the knurl is a a 45 degree diamond pattern, straight pattern (grooved), or a parallel 90 degree diamond pattern. Regardless, the grooved (straight line) pattern appears randomly in the 8 to 9-41 range and continues with increasing regularity after that.
