kent fish knife question

[tthman]

hi, i tried to post alink but couldnt get it to work so if sombody would id appreciate it, ebay 180138063468, ive got a couple of these in the black handle,bought awhile back when people couldnt give them away, and they ALL have 1 pin in the middle front and back i did have one of the brown ones but got rid of it,and cant remember if it had pinson top and bottom like this one.Did they eventually use pins on these. By the way the ones i have were bought in the 80s and 90s when hardly anybody collected them.So my question is werent the black and brown handled ones all made the same way, or did they chang through the years,thanks These knives are actually hard to find in unused condition thats why im looking for them, thanks
