Mystery Dinghy Make?

[Tatheelrod22]

I’m in the process of buying the dinghy in the attached photo. The seller has no idea of the make or year and I only get what you’re seeing here. I will want to make it a Sailing tender so I’m going to have to make the mast, dagger board, tiller etc. which I will do myself and enjoy doing, but will have a Sailmaker make the sail.
The make and year is not necessarily critical for any of this, however it would be nice to know. It may be a longshot but I find the seat configuration somewhat unique, so I’m wondering if that might tip off some of you forum folks as to what it is?

Thanks in advance!
