I think it's a Hawksbill 24 - see https://sailboatdata.com/sailboat/hawksbill-24
There's not much online but I haven't had a really good dig......
Came across this project boat on ebay today. Never heard of a Hawkwind 23 before.
Mast looks similar to hinged masts found on some Newbridge boats.
Location: Nottingham, UK. Cabin needs a lot of work.
