A Present from Blair Atholl

Raining nearly all day:-)  Time for an indoor shot methinks!  This cup has been in my family the longest  -  definitely from my grandfather's time  -  it's probably Victorian. (He was Head Gamekeeper in an estate near Blair Atholl). It looks like new because things of value were always kept behind glass in those days. It has a ceramic marking - see inset - but I couldn't find it even after trawling through dozens of internet sites. Have a nice evening, everyone:)
