I need your help on the disposition of the company engineering archive for;

"Economy Devices Corporation", New York, N. Y.

They made lots of steam loco appliance and appurtenances, most notable the "clam shell" firebox doors, marked "ECONOMY" across the top, that were patented in 1914.

I'll work on the patent info tomorrow.

These firedoors are on a large percentage of the smaller NG locomotives, like the Tweetsie's #12, 4-6-0, and the D&RGW #315, 2-8-0, and many of the other D&RGW Consolidations in the days of the small consi's tripple heading over Cumbres Pass.

If you are not sure, hearsay is welcome too!

No. 12 has a Franklin fire door, and as far as I know, always has.

Thats true, I remember now, it has a really light weight Franklin, that is not in the paper record of Franklin doors that survived long enough to make it into our hands, so far. I got it and the Economy ran together in my cluttered NG head. I'd like to find the blueprints to those early light weight & quite small Franklin doors too.

Franklin is one of the other company archives I'm also still searching for.
