The blades are unused with good snap and some spotting. The main blade is tang stamped CASE XX over USA and rear tang numbered 5254.
This is the'65-'69 Trapper with the Muskrat version blade. It is much rarer and more valuable than the regular Trapper blade.
I have added photos showing the difference between the Muskrat blade and a regular blade. Notice that the regular blade is wider and has a higher peak on the top of the blade. A nice and rare old stag Trapper in excellent condition. The item "Vintage Case XX USA 5254 Pretty Stag Trapper Knife'65-'69 Excellent Condition" is in sale since Thursday, April 16, 2020.
