Canadian = felt doesn't come to the edge. (Flag numbering roughly #266 through #1923)
Malaysian = felt comes all the way to the edge. (The rest of the production run after #1923).
HL 102's all had lightning rods.
It's funny but I can always tell my Canadians from my Malaysians when I'm cleaning my curios. The Malaysians go back on the glass shelves without a sound. The Canadians always sound like you are banging them against the glass. Trust me, I put all my HL's back very carefully.
