yeah Ross, thought about sending question, (how rare are these do your homework and have a look on ebay where you are selling,)
would have got some stupid response, like someone will buy it mind your own business!
I saw these listings and just laughed. Initially I thought it was "gtsales" (or similar) back under a new username but no, just someone who took their price guide from gtsales and tripled them....and wrote up a total BS 79 Mortimer description. It might have tweaked if they'd bothered looking at the 79 St George checklist they also listed!
