How old is your cupola? If it's of recent vintage I suppose you've already tried looking for whoever made it. I'm not familiar with cupola louvers. Are the tabs round or square?

Cupola is 160 years old, so I think the warranty is probably expired. The tabs are, IIRC, round. The shutters are set in a fancy arch-headed opening, but are basically plain shutters (with no center bar), but very wide. I have collected all the ones that have escaped the rails, but I'm sure some are lost. I regularly take window frames apart, and these shutters are made the same way (doweled), so I think if I can find, or cob together, enough louvers, I'll be able to make a good repair with (mostly) original material. Besides 30" wide by 4 feet shutters would be expensive, as you may know!

Sounds like making replacement louvers will be a custom job -- a fairly simple one, though, since you're wanting to do the actual installation yourself. You could measure the diamater of the holes that the tabs fit into, check whether all the slats are the same length and provide a sample (or samples) to a small custom furniture shop. Have them made from a reasonably hard, rot-resistant wood. I'm guessing the tabs could be cut with a plug cutter chucked in a horizontal mortiser, which would make it a pretty efficient operation.
