Cool. I think Ive seen the destination board frame (or similar) used to make up a tell tale. A dest. board hadn't come to mind.
A lamp would be cooler than a load derrick. I was just looking at acetylene lamps. I never thought about the gas source because of bottled gasses being so common today. The acetylene gas generator is an ingenious little device...drip water on carbide 😏 slick. I would have expected a parrafin, candle, or oil burner though.
