This is a very nice HMS Renown Sailors Cap, undated but would be prior to 1930's due to the cap style being floppy. Cotton liner also would suggest early production. Cap tally has been machine sewn to the cicumference. Three small moth nips to the top but do not detract.
Very light if any wear to the cap, very small size, apx 53, beautiful and scarce example. The item "WW1 Era British RN Royal Navy HMS Renown Sailors Cap Rare" is in sale since Friday, June 1, 2018.
