Nice little find , wendy177 !
If you're up to it , and have got some spare patience , perhaps you could do the job yourself & avoid the excessive fees that might come with restoration .....
From your images , I'd guess that you've got a less-than-common trunk .... the big thing , to me , is if the trunk is pretty solid & free from dry-rot .
If there's significant areas of dry-rot in the wood frame , that's a big set of problems , as to really restoring it & prob a job for a specialist .
If it is in solid shape & you just want to 'revitalize' your unit , it seems a fairly straightforward (& rewarding) home project .
