Did you find one yet? I have a T/C custom 12 bore that was listed on Gunbroker but I took it down last week. The stock is single trigger and used (in great shape) but it has a new, never-fired Toledo Armas (spelling) barrel on it. I got that barrel with a set that came with three barrels and a stock, all new. Sold all but the 12 gauge barrel and put it in a really nice stock. It is a percussion gun with a very tight choke. My dial caliper showed it to be around .685, or thereabouts. No removable chokes though. It is much tighter choked than my New Englander that is cylinder bore and should make a fantastic goose or turkey gun. Took it down but it is still for sale. or trade. Let me know if interested.
