antique THOMPSON gas space heater

Here's the antique gas heater mentioned yesterday when I showed the "radiants" that go with/in it.

It was made by the A. F. Thompson Mfg. Co. of Huntington W. V., their number 1016. The first couple pics show it front and back, (without the radiants in it) its lower portion is brown and tan enameled sheet metal and its top part is a similar pottery-based fire-proof material to the radiants, though much sturdier than they are, perhaps just because it is a solid cast piece. The two small holes near its front edge (pic 1) would have held a small ornamental metal fence rail kinda part (a rudimentary attempt at "safety"?) which is now missing, otherwise it is complete.

Pic 3 shows two of the radiants sitting in their normal position, with all six the entire front opening is filled. As can be seen their narrow top part simply fits in under the top rim and their open bottoms straddle the rows of iron gas burner orifices. Yuppers, those things get HOTHOTHOT with that blue flame on 'em...! ;-) :-)

Pic 4 is the maker's nameplate and brass gas valve on the end.

This one is kind of a fancy-looking example of these open flame heaters, I don't know exactly how old it is but don't think it would be out of place if it were sitting in front of a faux fireplace mantel hearth anytime in the last quarter 1800's or first 19's...??
