I appreciate the thoughts - but it's the 19j 501 (replaced with the 20j 501 in '57) combined with the two-line text that's giving me pause for thought
@X350 XJR 's was a '59 cal 505 - so no problems there
IIRC the two-line text came in around '58 - so it is just possible that an old movt was placed in a new watch but a jump of two watch movts is less likely
hence raising the subject for discussion
