I am having trouble trying to remove this movement from the waltham case, and assume it has a male stem,there are no case screws. I removed the screw from the case winding collar but still can not pull the female winding stem out so I can free the movement from the case. Any suggestions would be helpful! it is a model 1874 #2146108

It will be a male-stem & should have a case-screw on the back of the dial-plate near the outer edge of the Balance-cock foot, this is close to the Balance-wheel when putting a screw-driver there, so be cafreful. Can you upload some clear pictures?

Thank you Bila,hard to get a good photo but there is a case screw present to the left of the balance cock foot!This one was a puzzler
I appreciate your assistance and will give that a try
