Hi steve and welcome. I can't currently find any info about your gun. I'm sure it's in top shape but Euroarms of America is no longer offering that model. There are really no conversion "kit's" per say. Almost any perc gun can be converted too flint and vise versa. It's just a simple matter of changing the $150-200 lock and having the $ 40-100 breech plug replaced by a good gunsmith. Gunsmith's charge about $60 per hour and this would be about a 3-4 hour job.
If it's a drum breech and a common lock, you might be able save a few buck's, got a photo of the lock/section part of the gun?
