Nice score! SN confirming 1947 DOB. Also confirmed by the single line factory frame nomenclature visible in your photo. Might want to check for all the serial numbers a match. The only tilt I observe is a later vintage hammer. These early postwar Masterpieces my favorite vintage of an altogether great series! My own earliest SN K106xx and a bit too nice to shoot, Have a few later ones for that!
Congrats and...
My take
