Bill, would this then be a controlled part?
No. As I understand all the automatic parts for the M14 are not controlled. The reason is there is a downward piece with an installation hole on auto receivers. Because the commerciial M1A receivers do not have that piece, none of the M14 auto parts will convert.
It would appear that SA had more than one type of sear design during the pre war period.
Note the "hump" on this sear installed on a revision 2 trigger. Most of the rev 2 triggers are without the hump on the sear.
