I was hoping to get some informed feedback on a trade I was considering. The trade is a K31 for a Spanish FR8 Mauser. Both guns are in what I would consider to be very good condition. The core of my question is what do the informed readers of this forum think of the current market value of K31’s versus FR8’s. Is this a reasonable straight across trade? Does this sound fair to both sides? Sorry there are no photographs you will have to take my word for the guns being in comparable condition.
