Hand made wooden Baroque style German gold guilded picture frame

I have aquired a what appears to be a hand made wooden Baroque Style German gold guilded picture frame. It is approximately 29" tall and 37" wide; it holds a canvass/print that is 26.25" tall and 31.75" wide. It has several markings on the back... One is stamped or branded... hard for me to tell...: "KING-Rahmen handgaurbellet" (I think that is what spells/the printing is light) one looks like it was written in pencil reads: "M- 60.7/80.7 R+K Marketing" (note the numbers after the points are written as super script with underlines... just could not duplicate that here... see the picture below.) it also has what appears to written in pencil...: "BF 4597 60 x 80" and each marking is on a different side of the frame... I have lots of pictures and I hope that helps... any light anyone could shed on the approximate value of this item would be appreciated. Thanks so much...

Excellent
