I have what appears to be an identical brass. Do you have any more information on it?
This one is stamped :)
Manchester Ship Canal Company
There is a variation of this noseband marked "CARTER SADDLER BEDMINSTER BRISTOL". The village of Bedminster was incorporated within the City of Bristol in the 1890's. Carter was almost certainly the Bedminster harness makers cited by Mr. Ferdinand Huth in the Journal of the Gypsy Lore Society in 1940 as one of the very few saddlers who specialised in the manufacture of Gypsy harness. He was located at no great distance from Bridgwater, where the firm of W Watts built horse drawn caravans in the first half of the 20th century.
A rare white metal noseband.
Crocheted ear caps, worn by canal narrowboat horses, to protect against biting insects.
I also have one of these, I thought it was a 'one off' but it looks like it might have been a 'production' brass.
