Jim, check out Charlin "Le Superfixe" 12 on GunBroker. It's the only one I've seen (which I suppose proves very little) but assume it's probably same model as your gunshow 16. Been there a while and the price is dropping. The normally streamlined look of the breechblock on a Charlin sxs is lost with the deep frame on the stackbarrel. It's not in the '51 catalog (all the O/Us there have a toplever and sliding lock hood like Rem 32/3200 and a host of others). You mention a short stock; the stock on the Gunbroker item "looks" short also. Do you have a sliding breech gun? I have a very light Charlin 12 I got from the late Thad Scott.
