No doubt other workshops will do what you want, too. I've no idea of price, though...
Billet hooks on the cheek pieces and the cavesson nose band don't look all that complicated to me, but silver piping makes me think that it's a lot of stitching, so quite pricey. And where do you want that piping? Just on the noseband, the browband, or all over?
Flexible fit equestrian! My friend has one, it's very nice, their stuff is well priced and you can build your bridle to suit. Their leather always feels really nice too. I have bought a few of their things and liked the quality.
It's hard to get a link with what you are looking for because you have to build a bridle but they have the option to have a noseband and browband with silver piping.
Thank you. Great suggestions Keith & AE. Probably want the piping on browband & noseband. Will have to go window shopping - lots of bridles with white piping, can’t see silver piping being any different to white except for the cost if the silver.
