My HW-19 Mk3 uses a Berger Lahr 600 U/MIN(umdrehung/minuten, or rpm) 110 volt motor, cap spec 0.6 microfarad, though cap supplied by VPI is 0.68, measuring 0.653. Part number is
RSM 6 VG, reversible synchronous motor, 6 pole pairs(12 pole).
BL is now part of Schneider, checked site, part obsolete,but RSM51/6 is a close equivalent.
