I recently finished up a restore on this ER 200 (in the foreground, with the green base). I've had the red base ER 200 for awhile, and I'd been looking for quite awhile for the green base version. This one is a little nicked up, but I decided that constitutes vintage character. I believe that the green one is older, but the provenance of these ERs is so obscure that this is just a guess on my part. I'm always fascinated by these old brush handles that look so different, yet have the same model number designation.
I set this one with a Virginia Sheng 22mm silvertip at 45mm loft. The red base is set with a 22mm TGN finest. Both are wonderful performers. I think they make a nice couple, don't you?
