Either of these a 20ga O frame?

[Linn Matthews]

Looking at 2 used stocks. 178397 and 240807. No dimensions, other than length given. Would appreciate someone checking the book to see if either is 20ga O frame

Thank you, Linn

Would be interested in knowing where the .410 stock is.

The 12 ga. is a SC straight grip buttstock with trigger guard and the .410 is also a straight grip but with a Hawkins pad.
