[Tigers] Lucas dash switches

[Rollright at aol.com]

Hello,
 
I'm making a list from the Sunbeam parts manual (Tiger supplement) of the  
Lucas part numbers for the dash switches for my Mk 1A
 
I've got:
panel light       34943
main light        31946
screen wiper    31946
 
but I can't find the blower/heater fan number. Can anybody help?
 
BTW: I got a strange Lucas dash panel type paddle switch # 34943A   
Can anybody tell me where, what car, it was used on?
