I need #385 with option 1990 for Insulate single-hung window but the option range is 1910 through 1960. Can you supply me at 1990, Q'ty: 2EA. Thanks.

To get you started on the right path, you will need to remove the sash and weigh it on a scale. From there, refer back to the sash weight chart on the product to determine if any of our stampings will work based off of your weight. If not, get back to us with the weight of your sash and we will go from there. 

A professional from Aichi Pref., Japan says:
The sash is 11.4kg. Is 1960 good for this sash?

Yes, the 1960 stamping option should work for you. Get back to us if you should have any further questions.
