I am enjoying your build. Thanks for posting.
I learned a valuable lesson from this kit - if you see something you really like and want in this hobby, you should not wait to purchase! Many years ago, When I first saw this structure for sale it was produced by Magnus Models (I think that is correct spelling). While I was saving money to purchase the kits, they discontinued them. I was devastated! But I was equally as excited 3 or 4 years later when Berkshire Valley released the kit. I immediately purchase and put it in my pile of kits to build. Unfortunately, when I went to assemble it, I soon realized that it required more skills and patience than I could muster. Several years later, a gentleman at York had a completed structure for sale and I asked if he would assemble mine. He did a fabulous job and it was my favorite building then and continues to be over 20 years later. It is also the most commented on structure on my layout.
I am sure your customer will be thrilled to finally have it built!
Happy railroading,
Don
