M100B/BL/C Selector key dividers????

Was wasting time on eBay the other night and ran in to these:

Having mostly completed my 100B refurb, I was quite interested as my ESU didn't have these at all.  Sure enough, went to my manual and the parts list and I don't see anything that looks like this.   Not sure how these would mount or what the holes in them are for....perhaps a threaded rod of some sort???  

Was this really just something they added later to the 100C units, or did the B and BLs get these as well later in the game??  Or did it just depend upon what day your unit was built and whether they had them in stock at the time?

Andy,
These were provided free of charge in some area's, where the kid's (you know--ussin's little rascalls) figured out that if one was cleaver, he / she ( wannbee PC here), could "spoon" the ES, and get free selections---Ron Rich

Ron, what a great piece of historical trivia! Thanks for the info. Do you remember how they were mounted? Was it just a friction fit between the keys, or was there more to it??

Hi Andy,
On the ABC's I don't remember--on the later style, I recall that they would just fall out when the ES was removed from it's case.
