McCray Ice-box

I have a late 1800's / early 1900's McCray ice box. It has seven doors on it. 3 on the left side, 2 in the middle And 2 on the right. I recently acquired it while doing a demo on an old rock farm house south of Ft. Worth, Texas. It was build into the house, or maybe I should say the house was built around it. I have been told iceboxes this big were generally used as a butchers locker, possible in grocery stores, or flower shops. It's pretty rough, the bottom has some damage and actually came detached when I was moving it. It has been painted, including the hardware, which appears to be nickel and cleans up rather easily. All the doors have two lanes of glass in them except the big door in the middle, it has some kind of corrugated tin stuff on the inside which I believe looks to be insulated. Also this big door in the middle is the only door to have a mirror facing out, instead of glass like the rest of the doors. All the glass is there and intact, believe it or not none of it is even cracked. The inside has a few shelves and what looks like a couple of Dow rods. The drawers that held the blocks of ice are NOT there. This thing is approx. 6 ft tall 7 ft. Long and 32 inches deep. Any info on value, rarity, someone who refurbishes them, etc... Would be greatly appreciated. Thanks in advance. Shane
