That looks great in the photos, and excellent value. The Columbia yachts were known for being built like a brick outhouse. The midget ocean racer terminology came out of the MORC (midget ocean racer club) rating system in the US at the time. So they are "moderate ocean" capable............
www.baltimoresun.com/news/bs-xpm-1991-02-03-9113001121-story.htmlGoogle "columbia 22 restoration" or columbia 22 refit" and at least 5 sites will come up - some with excellent detail and photos.
Note that there is a Col22 for sale in Tas for $13.5K - at least it comes up on google not sure if it is still for sale.
As expected the interior photos shown in the advert indicate a tad of varnish needs to be splashed around onto completely sanded back timber - so what. The interior in the photos looks clean and cared for.
Suggest check;
the condition and age of the standing rigging,
the cabin sag under the deck stepped mast - if there is any. Easily fixed with beefing up the under mast support system with ply sandwich doublers each side of the existing support bulkhead.
Lift the floorboards and check the keel bolts - they are threaded into the cast iron keel. One of the restoration sites has extensive details of keel bolt renewal using grade 8.8 bolts.
Chainplates, and their bolts, also bulkhead in that area - hopefully no water has got in to rot the ply. Again this can be fixed......
As above well worth viewing and soon.
