Received a Buck 309 the other day that does not have a year code. The tang is BUCK with 309 under it and USA under 309. Three other things different from a newer 309 I have, are the shield which is raised above the handle, the spring pin is brass and the liner and handle are cut out for easy open of the pen blade. The shield is worn smooth. Is this enough info to get a rough idea of how old this knife is?
thanks
