The one on the Left is an Ever Ready 150 with a new 24mm Boar from Golden Nib and the one on the Right is and old Wood Painted Ever Ready 25J with a Best Badger from Golden Nib also, some paint lose on the top and I had to use a magnifying glass to read it, but I think it gives it character.
What kind of epoxy did you use? I have a newer brush with a chrome handle and I've noticed the bristles coming loose. I want to re-glue with something that will last.
