The serial number suggests that it is a Flues Model Ithaca hammerless double. Without more info, that's all I can tell you. It could be a very valuable gun, so get it appraised. If it is the Flues, it would have been made in 1919. This is from Moe in Iowa..Ithaca Gun Company sold a single shot lever action .22 caliber rifle from 1961-1978. It was the model 49. They also had a model 49R for three years that was a repeater. This was discontinued and the a lever repeater was made which was the Model 72 in the early 70s. The guns themselves were made in Germany by Erma Werke but, reportedly, the wood stocks and forearms were put on by Ithaca in the U. S. However, I am rambling. I bought two Ithaca Model 49 rifles recently and each of them has a a six digit serial number not far off from that listed in the question. One of my serial numbers is 277xxx and the other is 246xxx. In case it is not obvious the x in the serial number represents a digit that I will not reveal just to prevent some type of abuse related to firearms. As you can see the two serial numbers represent numbers relatively close to the questioner's. Note also that the Model 49 was in inexpensive rifle aimed at the boy's market so in 17 years I am sure there were many sold. Thus, there was probably a long string of serial numbers assigned by Ithaca to this firearm model.
