That site is very detail oriented as they even carry a selection of rust out parts like the tubular draft elbows on the Dietz pioneer street lanterns, there is also a link on how to seal fuel tanks with pinholes in them or in the historic section tell when a particular lamp was made, a detail change and color changes and the years they were done,the beacon lantern and the dash lantern i brought in during spring workweek were restored based on the proper color information using brushed on enamels as spray painting was not invented and brushed paint is thicker and last a lot longer and has more gloss retention that thin spray paint. I am currently restoring a brass 1894 double student lamp and will post a picture as soon as i find out how to get it done,as you can see, i am new to these type of forums.Im so late with this technology i joined Facebook 3 weeks ago to keep in touch with family members that communicate in that format,Gman.
