A lovely vase Michael, a very nice piece. I can't see any problem with your (as usual) spot on attribution. The differences in the CGR article seem minor and look to me as only minor variations of the same pattern, maybe just down to the individual cutter. The colours look classic as well, similar to others by Wunch and fits with the Hi Lo Sklo by Mark Hill images too. Jindrich may have more to say on this subject but it seems quite "clear cut" to me (just an English expression, sorry!)
