British badge and button lot from Ebay

I looked it up and,

In 1947 the cap badge adopted the Horse and Lightning. This badge has a strong significance to the role of the Corps. The cap badge consists of a Crown denoting the 'Royal' status granted them, the Horse and Chain represent the harnessing of mechanical power whilst the Lightning Bolt represents Electrical and the Globe represents the application of Engineering universally.

I noticed that one of the cap badges is the pre 1918 Army Service Corps type, prior to the addition of the Royal prefix, when they became the Royal Army Service Corps.

Also includes another unidentified object, any ideas?
