morning gentlemen, Can anybody shed some light on this symbol and the the differences available for this reference? Some seem to have none at all. Thank in advance
I believe that's pretty much the only manufacturer stamp for Speedmasters that is unknown. More importantly, how big is that case back or how small is your finger?!
From memory the best match I could find..Dutch Railways logo maybe inverted it was used for their fledgling space programme!
Wasn't there also the tree-shaped symbol on 145022s that was a mystery manufacturer? Or those star-stamped Omegas. I must be very out of the loop

Mine has the same mark. Also Moonwatch Only has a picture of a similar marked case back for ref 105.003-65. Production details:
