This part number is not known in the ldraw library used in MLCad et cetera. Ldraw
uses part number 87693 and that number is also known in Stud.io as an alternative
for 4502a.
So please add 87693 as an alternate number for 4502a.
[...] I think it appears in Studio just because Ldraw uses it, as I think Studio uses that library, but we don't know if Ldraw got their ID from somewhere specific. (29 months ago, Jan 19, 2022, to Catalog Requests)
