old mounted bayonet question

[SEATJERKER]

...Col.

...I have an old bayonet that that been in my family's possession for a long time, and I don't have any way to post up a picture, however my Father tells me it's from the Reveloutionary war...

...it has a round upper cylindrical with a L- notch in it, and drops down about 2 ", and then the tri-sided blade is about 12-14"...

...the tip is twisted a bit, 3-4 inches back, and dear dad tells me it was probably stuck in someone, and the warpage is from the metal not be tempered back that far,( I'll go along with that) , and someones ribs did the misalignment...

...any idea of value, or date, maybe British for all I know...
