If you would like to contribute serial numbers to that database, they will be gratefully received.  Sometimes a single number can make quite a difference in sorting out some of the mysteries of the Gray Book. Photos with serial numbers are most helpful.  If you send photos, they may be added to the library or used on the site.  We will request permission for anything used on the site.  Some collectors prefer to remain anonymous and we will respect your wishes if that is the case.  Otherwise we will acknowledge you.

Looking forward to hearing from you  jim@model92.com
