S Mint style

[lineop3]

I'm wondering if this is the correct mint style for this year. It doesn't resemble the 1941 styles on CC, it resembles the 1940's. Notice the curve on the bottom, it turns down not up like the others.

There two styles, large and small.You appear to have the smaller of the two.

It is the smaller of the two known MMs for '41, MMS-002.
