Full Stock Flintlock Maker Help??

[RoaringBull]

A friend of mine was recently given a flintlock rifle and wanted me to help him find out some information about it. 

Overall 58 inches long. 42-43 inch barrel. Patch box has a bottom release button. The double set trigger works well. The set trigger needs slight pressure to set the lock to half cock and full cock. The lock is decorated below the frizzen with a small fern or coastal rocks or maybe both. The lock has a name. The middle name is Dirks or Darks and the last name is definitely Marrante. The first letter of the last name is not readable, but may be Vanrn, Venrn or Oenrn. Plus he had to reharden the frizzen as it was very soft. 
One more thing, the barrel mic'd out at .345 but a 5/16" brass ramrod only went in about 1 to 1 1/2" and became stuck.

Here are some pics.  Sorry there is no good pic of the engraving on the lock.

    Are you sure it's a antique? Looks more contemporary to me, with a hand made lock.     AL

No sir I am not sure if it is. But I figured I would ask the biggest group of experts I knew of and this is it.

Look under the barrel please.  Anything?

My opinion for what it's worth...

Blued barrel, walnut stock, simple patchbox, unlikely period finish. She's contemporary.

    Is there anything marked on the inside of the lock? The area where the lock plate and pan join looks a bit unusual and it may be one of the Spanish or Italian locks imported back in the mid 1900s. The rifle does look like a lot of the guns made back in the 1960s and '70s.

Think I saw a lock very much like this recently.  Was definetly not original.   Assumed it was something produced during the fifties or early sixties.  Not too refined, that's for sure.

Back sight seems high for an original and the oval inlays look a little like stampings with the rounded edge out. Lock profile and feather spring look like ones I used to see in the Dixie catalogs and used on their old Belgium squirrel rifles. Maybe its an antique repro. Kind of nice though. How does she shoot?

That lock is signed with both a maker and location.  However, the picture is so bad you can't make it out.  Maybe he can look at it under a magnifying glass.
