hi back again ... the Redfield model 70kt and the model 102 I get on EBAY also type in "Redfield sight" and look though then or type in "krag" and look though those listings ... Here what I do if you find a Redfield Krag sight there really expensive 100 to 200 dollars most of the ones I find are under "vintage sights" or I buy ones that were dropped and all bent up and I straightened them out or get other model 70 or 102 and trade parts and fix them ... also I have got a few that were rusted and cleaned and polished them and had them re blued and sold them for a lot of money ... If you buy a sight make sure you get the longer screw with it there really hard to find ...
