Thanks.
I think the Merkel 147 of DS was also plainly stamped on the water table and in the middle 90s. (2 94) Feb of 1994. Unlike mine.
This code however on my water table would either indicate a later-or possibly earlier shotgun build date,
as Merkel revised their code. Maybe Oct of 2004-UNLESS this is a different Model with possibly another code. Not likely based just on model.

This 20 GA Merkel is either a 147 or (possibly a 1620-doubtful).
At any rate, BBL length is 27 in, IC-M; SS trigger; straight stock-oil finished. Minimum engraving. It is possible that it is a 16-yr old gun, or older.
Color case receiver shows aging and use.
