A bit of a silly question really, but what is this switch panel out of:  Just a small curiosity to us. Nothing important. Cheers. |

Caburetter should be spelt carburetor (American spelling) or carburettor (Commonwealth).

The instructions are odd!
Full heat is usually applied for approach and icing conditions sure, but carb heat should always be 'Off' for the actual landing in case full power is suddenly required for a go-around.

Well I guess it will have to remain a mystery. We were wondering because after the quake here we checked roofs etc and found this in the old guttering of the garage and the suggestion was that maybe it fell out of an aircraft some years ago as we live just off Springs Road near Wigram.
Cheers.

The fact that you have such an unusual item is interesting Sean, but the finding of it in the shed's guttering is great!! One of those real mysteries. Maybe you should send the photo and the story to an avation magazine, if nothing else it will make people smile.

May just do that Dave. It just struck us as a strange find and then the suggestion was made to us about the possible origin being something flying over once upon a time.
Cheers.

The carb heat placard is a strange one. It seems to be just an advisory. There doesn't seem to be any directions over what to do to change the setting. It would have thought it would normally have "Carb Heat Hot : Pull"... or some arrows to indicate direction of travel. or something along those lines.
If no direction info then perhaps the the positions are indicated by moving a lever to be in line with either of the "Full Cold" or "Full Heat" labels. From the orientation of the writing I would say that the lever movement would be in the vertical plane.
Almost every GA plane I have flown has carb heat as a push/pull control. If anyone knows of the cockpit layout of an older aircraft with the carb heat control lever moving up-and-down, that could be a good clue as to the origin...

Although you don't say what material it is made of, it looks to me like an engraved decal of "Trefoilite", that three layer hard plastic material that was once so commonly used.
It could be that a previous owner of your house was an engraver or worked for an engraver. The spelling mistake could account for it never being fitted to an aircraft.
It might be a production defect piece of scrap. The homeowner was probably using it to scrape patches of moss or algae off the roof without damaging the paint (as you do).
One edge looks a bit worn in that regard.
When I was in the industry it was very common for aircraft manufacturers and maintenance facilities to get the local engraver to make up decals. Mistakes were often made, not always at the engravers. I have seen the decal drawings come out of the drawing office with spelling errors!
