Neutral Safety Switch ID Help - not a 49?

[Dan O]

I blindly bought this neutral safety switch on eBay awhile back and it is not for a 49 Buick Super or Roadmaster. 
 

anyone know what it fits?  I would like to sell it if I can figure this out.

Buick parts books are identifying your mystery switch as a 1997847 back-up light swtich. There's a current Ebay listing for it.

It will not fit in my 1949 Roadmaster.  I promise you that.  The screw holes are wrong and the arm is too short  did Specials have Dunaflows? Perhaps it fits a manual transmission for back up lights?!

From Buick Master Chassis Manual:

 

Group #2.698  Switch, Back up light     part #1997847 fits 1949 50-70 series and 1950-1951 All w/Dynaflow

 

Group #4.038 Switch, Neutral Saftey    part #1997838 fits 1948 thru 1951 All w/Dynaflow

 

I hope this helps
