Small electrical component to identify.

Bearing the numbers ZC10752 and what appears to be the tiny painted number of 10A/14470. 30mmX25mm in size.
Miscellaneous radio (wireless) equipment according to the 10A part, but looks too ‘modern’ to me to be wartime issue. but was found in woodland at the rear of a known dispersal site.
I know some of you like a challenge!
