This will just add a little. I owned a Bristol 26 and a Bristol 27.
I recall the 24, originally made by Sailstar in Bristol, RI (which Clint Pearson bought out, forming the better-known Bristol company) is much roomier than the Alberg designs (22, 27) but had keel problems as it was encapsulated lead, and not often real lead. The Bristol factory tended to throw in whatever metallic waste was on hand, and then bond it in with resin.
There's several 24 owners on the Sailnet Bristol page (or maybe they've moved to Jazznet) but the Bristol clan, as a whole, are very helpful. Before Sailnet crashed, some five years ago, there were 220 Bristol owners on the page. The leader of the Bristol clan is Massimo, at email@example.com
and he can direct you to the 24 owners.
Email me back if you can't find him, and I'll dig up the other addresses.
