These are brand new Dansette Record Player control knobs that have been reproduced from the originals found on the brown and cream BSR UA8 deck.
 
These control knobs have a solid back with the correct sized holes to fit the deck control shafts. You will not find these anywhere else. 
 
Price includes 2 x control knobs.
 
Tips: Always make sure the shaft is clean before applying the control knob. Some control shafts may be on the smaller size so you may need to use tissue paper for a more secure fit.
