I just bought Ithaca Flues from about 1919 and on the left side there is noticeble crack in ther frame originating from corner of horizontal and vertical face of the receiver protruding down diagonaly toward the back of the receiver. Guy that sold it to me on Gun Broker propably not even known of the crack but there was no option of return so I am stuck with it. I would like to hear opinion of experts if this could be something that was there thought service life of the gun. Have anyone came accross similar defect on Ithaca Flues. Beside crack gun had some deformation of top and bottom spur of the receiver. When correcting it I was astonished by softness of the metall. It was like gun was made of lead. It was so unbelievable easy to bend. I wonder about steel quality in those days.
