The interior shots clearly show the classic glass/resin color, weave and even what appears to be protruding glass fibers in the ends.
I have no idea of the brand or model.
The deckplates are standard fare at any marine supplier, so you should have no problem replacing them.
Judging by the paint lines in the cockpit, it appears that the boat originally had foam bulkheads. Minicel bulkheads would not be hard to make and even 'glass bulkheads aren't hard to fabricate.
It's somewhat hard to tell from the photos, but it appears that the boat may have been painted and may not have any gelcoat. If so, that would make it easier to repair and restore. You could sand it down to the glass, examine it for structural damage, make any necessary repairs, then prime and paint it.
The damage at the stern looks bad enough that it is likely to leak. Expect to do some fiberglass work there. The "soft spots" under the seat could indicate damage, but it could also just be due to the wide, relatively flat area being naturally more flexible. It's an easy area to repair or reinforce, since you have good access to both sides.
The stripe at the hull-deck joint looks to be largely cosmetic, rather than structural, but the inside seam appears to be well executed.
You can make a simple foam seat without too much work.
If you're looking for a project boat to learn about repair and restoration, this looks like a pretty good candidate. I've got some tutorials on my website: BrianNystrom.com It's a work in progress and I'll see if I can get the bulkhead and seat fabrication tutorials posted in the next few days.
