A while back I bought two vintage GE miniature lamp catalogs on eBay. I finally had a chance to scan them and share them. I uploaded them to Scribd. You should be able to download them as PDFs from there if you have an account:

First catalog is from 1949.

Second catalog is a little newer but I don't know the exact date.

You can upload pdfs to this site as well..
