1930s 7 piece, 3D, 12' long porcelain Dutch Boy Paints sign

This is 7 different pieces of metal covered in many different colored porcelain. It has ALL of the metal Ribs/Frame pieces that the bolts attach to on the back of the sepparate pieces. I also have 2 of the original brackets that it is hung on. There is one bolt and nut missing on the blue and white bottom part where it attaches to a bracket behind it. All of the other bolts and nuts are original to the sign and no others are missing. I am also starting to think that the bolts are brass but I'm not for sure about that yet. I counted 11 chips in the main visible areas of the sign ranging from a cm to a inch and a half and one along the side of one of the red T's is about 2 inches long but very slender and then there are a total of 16 brackets attached to the sign and probably 8+ have porcelain popped under the bolts or brackets.   The 2 large pieces that are white and have no lettering are in very good shape with the above mentioned chipping under the brackets except for the one that has a 1.5" chip above the red letter D along the top of that piece. The red lettering is perched on brackets about 4 inches off the white fields and the Dutch Boy center piece. The red lettering itself is welded to 2 long brackets that are coated in white porcelain, that run the entire length of the red lettering and they are attached to the brackets that are perched on the white porcelain. This entire piece has chipping in several places along the long brackets and then there are several areas of chipping in the red letters.I just went out and took pictures, with a tape mesurer by the chip, of all of the chips. I will send those to you if you request them. The blue and white bottom piece has a total of 3 pieces plus brackets that it attaches to and the curved pieces take it to be about 4" above the White pieces below it.I have not been able to find a chip on any of the 3 pieces and because of this and because of the color retention, I would rate it right below a 9 out of 10. The last piece that I will describe is the most breathtaking and in the best condition. The Dutch Boy center piece has no visible flaws that I can find! All colors look to be perfect and there are no chips. I think that is partially due to the fact that there are no brackets that attach to this center piece. The red lettering Boy above this section also seems flawless. I would rate the center section at a solid 9 out of 10 and maybe a 9.2.
