^ I H ^

Found by SP in Paisley area

Unknown maker.

Find location would suggest Scottish origins but….

Very much a conundrum  –

Upward pointing arrow, then a stylised I and H and then another upward pointing arrow – of course this could read the other way too if they are downward pointing arrows – H and I

Any ideas.

Measures 8 1/2″ x 4″ x 2 1/2″
