I believe you Rich.
As I said before I really wasn't making a study on this and have only noticed it on a few of the Malaysians.
However.
I went through some of my notes and I did find where I have written down that a Canadian #2341/5500 had the shellack finish.
I retrack my statement about only Malyasians having the shellack finish. Since this seems to be an interest I need to start tracking them.
