You really need to give more information to get a good answer. If this is a double barrel shotgun, sn 272839 is what is called a Flues model invented by Emil Flues, introduced in 1908 and produced through 1926. It was offered in five gauges and 11 different grades and the value of the gun depends on the condition, grade, features, and, to a degree, the gauge. If you want a reasonable estimate of the value, have the gun appraised by a reputable gun smith or Ithaca collector.
The serial number indicates it is a Flues Model mfg. in 1915, the T would indicate it is a Trap gun, and very desierable to have if it is in decent condition.
That gun was made in 1918. that is correct if your Ithaca MODEL IS FLUES & NIG http://www.ithacagun.com/pdfs/serialnumbers.pdf
See www.diamondgunsmithing.com. That serial number falls in the range of a Flues single & Double barrel category, year 1924.
colds and flues are caused by bugs and viruses and tiny little specs.
That is a tough one. Try writing to The American Rifleman (the NRA magazine) to see if they ever ran a disassembly article on the Flues model (although that is unlikely since the Flues was made from 1908 to 1926). You will likely have better luck contacting the Ithaca gun collector clubs and see if anyone ever drew one up. That may cost a few bucks.
Ithaca Gun Company of Ithaca, New York was the manufacturer. "Flues" refers to the designer. These double barrel, two-trigger, side-by-side shotguns were made from 1908 - 1926. Check out http://ithacagunrepair.com/page5/page23/ for a list of serial numbers by year of manufacture.
