There was a Blackbird sold on ebay today #313475270651. The seller had a rating of 2. The seller described the pen as a Big Blackbird but the pics did not show the right imprint and the nib was wrong. I asked the seller to confirm that it was a Big Blackbird and they said that the nib showed BIG BLACKBIRD although the nib was so dirty that I couldn't confirm his comment.

If the buyer is on here then you may want to check the description against what you receive and have the knowledge that the seller is already on alert.

Must admit, that I am always cautious about sellers with many items for sale who appear to have been born again.
