Hello Sontaran,
Thank you for your prompt response. This item was discovered in a suitcase of Masonic Aprons, Collarettes etc that one one of my Sons purchased about two yers ago at a local Car Boot Fair. He has only recently passed these to me. I am 85 years of age and a PM - Initiated in 1971. There is a Red Apron with the Collection which reflects your observations, having an embroidered circular Badge Logo with the lettering 'MIDDLESEX' and a Cornucopia overlying a set of Compasses within the circle. A matching red Collarette has a similar 'gold' logo on its Jewel with the same lettering - beautiful.
