Can someone tell me what kind of turret is on this old Stand-Modern lathe? I need to buy a boring bar tool holder for it but do not know what type of turret this is and can not pick out a compatible tool holder. It is 9.75 in. in diameter. It is circular and does NOT have flats on the circumference. Id and pics below.
