Can't give up on it

[Drew Hause]

Mark: thank you for posting that frightening illustration of the result of misguided and inexpert chamber work. Was the chamber extended also? What is the current chamber length? Researcher has established that at least until 1926 (after introduction of the NID) 20g Ithaca chambers were 2 1/2"

I took the liberty of sharing the story and one image about 1/3 down here

I do not believe Brad or Kirk would attempt to repair the chamber, but anxiously await the rest of the story. It might be possible to sleeve the chamber and barrels past the thin area, but as a 20g it would probably need to be to .410.
Fitting a donor 20g fluid steel Flues barrel would likely be much cheaper.
I would also not suggest full length tube inserts in light of the cracked chamber wall.

Men
Thank you all for the thoughts and responses. I have recieved a pm with a potential matched set. Pictures forthcoming.
I also exchanged pm with Brad. He has agreed to look at the barrels.
Drew - Thank you for linking your paper. I read it last night. Very well done.
Steve I cannot sure of loads as it was many years back. I expect I would have used RST to test but cannot be sure. I am not sure either what Jason used. I am just forever thankful he was not injured.
Fingers crossed on the potential match. I will of course follow up here if we managed to save the old girl.
