Rugby School & Inns of Court OTC badges
 

I recently acquired a collection of badges and associated items and amongst them were these ones. I have very little knowledge of OTC badges and would welcome any observations you can offer as to their use, time period and originality.

The collection itself appears to be associated with a chap who attended Rugby school between 1903-08 & served in the Inns of Court OTC between 1914-15 before being commissioned into the KRRC. I have absolutely no idea whether these badges were ever used by him or simply added at a later date.

Any opinions you could offer would be most welcome as these are really outside my normal collecting interests.
