English Ca. 1770 more or less. Colerain 29" swamped .58 rifled barrel, Chambers early Ketland lock, good old Iowa wallynut stock.
There is some precedence for a gun like this, There is a fowling gun in "Great British Gunmakers" made in the 1770's for the Duke of Earl...or some such fellow.... with an abbreviated trigger guard like this. Also, English coach carbines were sometimes made with out buttplates. So, I stretched reality a bit and combined those features into one gun. Plus the lack of standard lock bolts, which was done on English guns on occasion also.
The wood is as hard as wallynut gets, but the grain through the wrist is less than ideal, something I wouldn't use for a customer's gun. So I figured it to be ideal for a gun for me. I sort of reinforced the wrist, the screw that holds the rear of the trigger guard and the screw that secures the thumbpiece are both 1" long....trying to head trouble off at the pass. Anyway, I just got done shooting it and no problems. In fact it's incredibly accurate, first five shots are one ragged hole. Deer beware!
