Still available here in Germany. KAMAR still have 39 sets in stock, Linear-A about 30 (though many listed as limited stock). Last release mentioned over at Benno's was April 2021.They are also still on the Redbox homepage (http://theredbox.com.ua/alliance.htm), so I guess they're still in business but given the slow output of RedBox (at least compared to Strelets) perhaps they only release a few new sets each year.
There are still some here stateside. I was wondering if there was any news about future projects from them. guess I didn't quite get the correct thought out (lol), of course as I get older that happens all too often. Thank yall for looking our for me.
