I got the tool post and holders today. The owner informed me that someone else was trying very hard to buy these out from under me, and was pushing to send an e-transfer to pay for them even. But The seller is a good lad and I had already offered to sent payment to secure them and he said it was not necessary. So I think that is a sign I got a good deal despite potential issue.
I do not think the tool post is an authentic Dickson, but I dont know them well enough to say definitely.
The tool post has a central bore, which I assume is to go over a short post. It has 3 bolts around the perimeter and one indexing pin instead. I'm not 100% sure that this will fit the lathe without modification to the tool post perhaps.
However, it came with a good assortment of holders that make the purchase a good deal.
Ten straight tool holders, one morse taper holder, five boring bar holders w/ hole, and three vee groove holders.
At least 3 holders are authentic... the three vee groove tool holders are marked.
I'm a little sad that there is no cut-off tool holder, but I cannot complain
