Slipware SHK SIK hen & chicks eggcups

Slipware eggcups I’ve had a while.
I always presumed they were Thoune type pieces
Signature on bottom. SHK or SIK Might they be British Studio?

Pretty little things. Trouble is, there is not a lot of money to be made out of eggcups, and that decoration is not just a simple stylistic flourish. Cannot think of many British slipware potters doing egg cup sets. Don't think Winchcombe had much to do with them, ditto for Coldstone.

They look like Swiss, Thoune slipware to me

Thank you Philpot & Naomi! Swiss then probably.
