So, there is a press release posted on the Muhle site that mentions a new, limited edition brush in the new "Retro Series" to be released next month. No pictures are available, but the knot is to be 25mm. I am very curious about this. I haven't received a response from Muhle to the email I sent them. Does any one know anything about this? Care to speculate on the style? There was an eBay listing for a vintage Muhle brush, two tone, which may be the style.
