BSR Record Player Stacking Changer Spindle + 45rpm Adapter for 210-610

This is the stacking record changer spindle, plus the 45 rpm adapter changer spindle for most BSR turntables of 1970s vintage, including models 210 through 610 (not 710 or 810), plus others. This also works on BSR record player/changer models built into console model and compact stereo systems. Many of these record players will have printed or stamped into the platter mat area circling the single disc spindle wording to the effect of Made in Great Britain by BSR.
If it remains available, I also have a separate listing with this spindle plus the 45rpm record changer adapter.
