Yes, I did. It was my first 400 type brush. http://jrshaving.blogspot.com/2017/03/jayaruh-400-type-brushes.html
Jim @Jayaruh is a Supporting Vendor here at TSD. You can send him a Private Message (PM) to discuss purchasing one or more of his brushes. Here's a LINK to his previous deal. He's made many members happy with his brushes - Check 'em out HERE. (I am the proud owner of #130 )
The 400 arrived. A No.3 (thought to be unnumbered). Very good and clean condition. I scrubbed with some Scrubbing Bubbles and then soaked in hot water and Dawn over nite. Only hand buffed with a polishing cloth did not use any sandpaper. Shined up nicely but can still see some faint usage marks - which I think will leave to retain it's character. Have not tried to unscrew just yet as I'm enjoying the view - for now. Purchase Condition .
