Yes, I bought my 1765-EM novodel 5 kopek coin (Brekke 205) from him last September, and the transaction and coin were both very satisfactory. This seller turns over a lot of coins, so maybe he was just careless. Besides, some references do not list any difference in rarity between the two mintmasters, although more recent ones such as Kazakov do. Maybe he thought it wouldn't matter? 
Hi Bob. Just caught your mention of the B205 1765EM novo 5K. I have the B206b version bought in 2000 at the Goldberg Hesselgesser sale. Just curious if it is "en plastique" as they say in Paris. Mine has an NGC tag, but at the time NGC wasn't putting the big piataks in slabs, so mine is in a poly envelope. Even though it's a novodel, I love the big Russian coppers, and, as they were collector coins, they're usually in very nice condition. Maybe you could post a picture or is it already on omnicoin? Mine is. (collection = ahlbeback)
