Thank you for your answers .. I will formulate my question differently ... whether it is possible to alter / modify the sewing machine with high bed in a machine with a rotating / movable horn for lock stitch? .... I'm going to buy a Russian machine specifically for rework if possible .. .
In the Russian classification --- an industrial sewing machine class 236 PMZ Podolsk Engineering Plant - single-needle, designed for sewing leather boots and backs to the rear for nastrochki belts.
The machine sews two-strand shuttle line.
thanks for any commentary
