Howdy. This is my first post at TFL after lurking for the past month or so. Great board. Anyhow, yesterday on an impulse I picked up a used Ithaca 37 in 12 ga for $129. The gun has a ringtail forearm and checkering on the grip portion of the buttstock. Wood is walnut and the receiver has the usual engraving. The bbl. is 28", no rib, Poly-Choke. Condition overall is about 70%. This is my first Ithaca ever so I have some pretty basic questions. First, given a serial number 190xxx, what do I have and how old is it? Second, can anyone direct me to some disassembly instructions? Finally, are there any maladies that typically afflict Ithacas? Anything I need to look for during tear-down, cleaning or test-firing? Thanks in advance. I am very excited to find out all I can about this gun before pheasant season starts up.
