Jon makes a great point.
The first recorded flute with legitimate Tavistock address (No. 1, that is..) is serial number 3884.
This one is said to be 2414?
Also a problem. The quattrefoil mark does not first appear until between #3230 and #3246. The seller's photo shows it has the quattrefoil.
Cocusflute notes well that it could be a flute that says Rudall Rose.....but I've not yet seen a forgery with the Quattrefoil mark. Not to say it doesn't exist, but I've not seen one (and not heard of one from anyone else).
It's POSSIBLE that this flute serial number is actually 4414 or 5414 (though I doubt it....the holes are too small for the higher number).
The foot joint has overlapped C-C# keys, which goes out of vogue at about #2928 (though it reappears on occasion).
This is certainly a strange Rudall, though I don't doubt the left hand piece is for real. The barrel is a replacement as is the lower ring of the upper headjoint.
The right hand looks fine from the short-F touch. The long-F and long-C are retro somehow, though perhaps fixed for someone way back?
One thing is sure to me: it is NOT #2414. The flute just doesn't fit properly into that frame.
hope this helps.
