RASC KC Bullion Badge

[Fatboy Ken]

Hiya guys

Your help is needed here please, I'm looking at an RASC Officers bullion cap badge (LIKE KK2117) !!!!

http://cgi.ebay.co.uk/Royal-Army-Ser...item2a11a7c533

KK2117 says In Gilded Metal !! "Crown raised, leaving a space between the base of the crown and the top of the Garter". Sealed 12th Feb 1949.

Is this a genuine Cap/Beret Badge from GviR period ???
(All Officers badge centres are "RED", why is this one "Yellow")
The Crown is also touching the Garter in this Bullion Badge.

The measurments make this a beret badge, 40mm x 38mm
(When did Officers start wearing berets, with bullion badges) ???

Could this be a Blazer Badge of sorts ???

I want to give it a miss, but could it be a geniune badge, it looks like a piece of "MUSH" to me, even the RASC scroll is crap, but I'm new at this, and need some help.

Would you buy it ???
Cheers Fatboy Ken
