In search of replacement sliding glass door hardware

A handy person from Painesville, Ohio says:
Can you tell what brand of sliding door this is and if hardware is still available? The house is a Mid-Century modern built in 1968 and we are trying to keep and refurbish a lot of the original items in this house. The doors are in relatively good shape but could use some new hardware in some areas. Thank you for the help!

Hello! Your original lockset looks very similar to our 82-001, which is used by a brand called Crossly. There's a good chance that's who made your door. We sell this handle set, as well as a keyed version under our 82-001K. We also sell the keeper you show, which is our 89-004. These doors also commonly use the 81-001 roller, but that's no guarantee.

I'm not sure what else you made need, but we usually like to take these sorts of cases on a part-by-part basis. If you show us what you have, we will do our best to match it up. Just let me know!
