Kart .22 Magazine Value

I have some original Fred Kart all steel .22LR magazines and am wondering what they bring these days. Contemplating selling but don’t know value in today’s market. Any help would be appreciated. I have 5 left all in really good condition. 

Thank you,
Steve

To be honest I don't know the value of Kart magazines. You didn't mention if they were used or not. As quite a few know I'm building my version of a .22 conversion and would need magazines. I'd be interested in them if the price was reasonable. They may or may not work in my conversion but it may be worth trying them. I do remember back when Kart conversion were being used at Camp Perry and other matches. If my memory is correct they had feeding problems. But don't know if it was the fault of the magazine.
 If you determine the price please notify me I may be interested, few photos put on the forum will help!
