LOL.
There were two brick fireplaces in this house when I got it in '97. Both had fire screens of some sort, and both had fake log sets in them. One had a cellophane wrapped cylinder that rotated horizontally, lit from inside with a standard light bulb. The cylinder had an approximation of flames colored on it. In front of that were fake logs with a translucent area. The other set was a bit more interesting. Instead of being motorized, it had a propeller on top that was designed to catch the warm air currents caused by the light bulb, and turned on the Z (vertical) axis. They both worked after a fashion, but after I sealed the front of the fireplaces with plexiglass, there wasn't enough air current in either of the fireplaces to turn the propeller. And I didn't like the noise the motorized fake log set made.
One thing that floored me is that while the fireplace in the 1941 era living showed signs of years of use, the fireplace in the '65 era family room was obviously added later on, and had no signs of ever being used. I found that hard to believe for a 30 year old fireplace.
I got some new grates for both fireplace and tested both with real fire. But fitting the plexiglass draft seals after a fire session was sort of a PITA.
After a while I replaced the plexiglass draft seals with good fitting fireplace inserts. Both work pretty well, although I think the '65 fireplace draws better than the '41.
