Ah yes, Esci that which got me started in the braille scale madness. I still have the "Don The Long Retreat" . picked it up at a real jem of a mom and pop hobby shop that was owned by a quaint old married couple called Harold's Place in Lynn Mass. some 20-25yrs. ago. Picked up a lot braille stuff there including diorama kits from Nitto and Fujimi. Miss that place a lot.
