No! And never had been! 

Some time ago MT-Propeller distributed JIHOSTROJ governors of model lines P-ABC-XXX and P-ABC-X/Y. It was labeled by MT as MT product, but always this governor was designed and manufactured at JIHOSTROJ. At the present time MT is distributing governors of its own design and manufacture and JIHOSTROJ does not distribute governors via MT! See explanatory chart.
