Arcadia Sliding Glass Door Hardware

We recently purchased a 1954 Mid-Mod in Houston, Texas. Our house has 5 sliding glass doors, 3 of the doors have most of the original hardware. The hardware has Arcadia stamped in the handles. I believe that all of the doors are the original Arcadia doors that were installed in 1954. I am looking to bring all of the doors back to their original condition. I have pictures of the original hardware and would like to hear from anyone who might be able to assist me with locating or reproducing the original hardware. 

Thanks
