I just ran across this on ebay. I’m not interested, and it may be firewood, but I thought I’d pass it along in case it is something worth looking at:
This one, by Rod Cameron, is certainly not firewood 
. Has a screw cap and a foot register 
.
I especially love this part:
Fresh from an Upstate New York Estate Auction!!!
And the pic with the two hand sections separated by about 5 mm and the big bend in the flute. Could also be someone without a clue how to put a flute together, or a real problem. Maybe one of our antique-flute gurus can chime in.
That is a lovely flute!!!

The Cameron copy does not look like a Grenser. It looks more like a Rottenburgh.
