Not an every day brand so worth taking a shot at. Penn-Craft bowler in a size 57 or 58. Size tag says 1/8 but given the measurements I believe it was adapted for the European market. so likely an English size 7 1/8. Brim at a good 5cm and the crown about 12cm high. Aside from some foxing on the liner in excellent condition.
