the pics below are of a 3 7/8 in. Camillus muskrat, sold to me as coming from a knife collection, having bone handles and "a tue collectors knife in mint condition". well, it is in mint condition, but i cannot tell if handles are bone or delrin, and unlike all my other Camillus', there is no pattern # stamped on a blade. any thoughts on further IDing this knife will be appreciated; age ?, bone ? end of days knife ? thanks roland
