removing a tudor crown

[MrClean]

picked up another 50s tudor with a FEF (FHF) 390 movement - curious on removing the crown. From what i've gleened reading various threads, there's usually a screw that controls a pawl that i assume is riding or seated in a detent groove on the crown stem, that keeps the crown from pulling out.

i've got decent mechanical background, but absolute no watch experience and all i'm looking to do is pull the crown so i can remove the movement and then the dial and check the 7928 dials i've got to confirm they are 7928 dials, ie that the feet are in the correct position, before i send one out for repainting or restoration.

i've identified two screws i "assume" would be one of the two screws - #1 sits offset above the stem approx 2.5 - 2.75MM, the other, #2 slightly offset below the stem maybe 1.5 -2MM.

figured while i'm waiting for the correct screwdrivers to come in, i'd see what folks here, with more experience might say or suggest.

tks in advance
