They made these scrimmed in numerous animals and many variations, the 80 tys or 90 tys 30 to 50 dollars ( each) unless you have something rare. This estimate is for the large LB-7 type model. ( the boxes help.) This would also be the range for the brass liner lock 225 types of patterns. (NOTE these often bring less on ebay ) Your handles are imi ivory Schrades, name is micarta which in effect is a brand named material called delrin which is a type of plastic. Funny it sounds less exotic than Imi Ivory. There are so many variations that really a picture would help but in general most fall into this range. ( NOTE extimate is for unused knives used knives worn ect of course affect value ). Sorry I could not pin the date down but without a pic it makes it tougher and there were a ton of these type issues. perhapes one of the other guys has a listing for these two. Nice knives to display and add to the collection. Good hunting LT PS I just remembered they did a buffalo edition that came in a wood box with a tiled bison picture on the lid that set would be worth 50 to 100. That set came out a little later.
