Whiskey trinket box (Hereford, HR1)

Hi, a bit of a long shot but does anyone have a collapsible stainless steel trinket box ( similar to picture ) that they no longer require. The outside casing to our collapsible whiskey cup has been misplaced and cannot be found anywhere and we are gutted to say the least as its a family treasure passed down to us...please see pictures....if anyone can help we would be so grateful
