Well it looks like LM is there again, Reg did mention it in passing but didn't settle
It's the Alekseyev SM-4
The catalogue on the Airwar site lists the SM-4, but the page is headed SM-3, scroll down and the picture is repeated with the correct title!!
Google Translate
LM has control yet again! Thank you for aiding my decision
Reg ! Go for it
LM, New Balls please!!
