I'd rank Holliday and Brown at least as good as Charles Hill. Â HB ties are also self-tipped, which I believe CH aren't. Â T&A allegedly have their own tie-making factory for a few years. Â Allegedly.
I agree with H&B being on par with Charles Hill. Only one of my two H&B ties is self-tipped, however. The self-keeper is hit and miss on English ties, too. I have CH ties with no self-keeper and even Drake's doesn't sew its keeper into the center seam. I suspect that T&A ties at least used to be made by Charles Hill. The tipping that is used is awfully similar for them not to be. I suspect Ede & Ravenscroft of using CH, too.
