Looking for back and crown for a 1952 Omeaga seamaster

Hello, I have a 1952 Omega seamaster automatic with calendar at 6 O’clock. It has the square date window, the gold capping and hands and markers. The crown was replaced at some time in its history and the back has an engraving on it. I do not want to sand it out but would like to get a crown with the omega stamp and a back, does anyone have such a creature. I love this watch , it has the bumper 353 movement , ref#2627 Thanks for reading.
