@Strope Congrats on amazing "Drawer find"
Looks like an honest 2915-1/2 that has lived a life.
Dial seems to be in beautiful condition.
Watch has a couple of minor issues that might detract the most pickiest of buyers (such as the dented bezel, & relumed hour hand). But overall it is in beautiful shape.
The replaced crown is an easy swap with an original.
I don't know if you're intending on keeping it in the family or selling it, as its value could be a life changing sum to many.
I would value this watch at about $150,000 - $175,000 on a private party sale. (Given that the original movement is inside of course...).
Should you decide to sell it and go via an auction rout, just keep in mind that auction houses charge commission fees and a rather long pay out process. (normally about 4-6 months from the moment the watch leaves your hands until money is in the bank).
Whatever you decide to do, good luck! And it is great to see these awesome pieces still surfacing from the depths of drawers all over the world.
