JM:
Thank you for your kind words. I'd reached both of those conclusions before my post. When deriving the curves for the front, in addition to soliciting information on this forum, I asked a highly respected local reproduction cabinetmaker his opinion. He suggested that I should err on the side of "bulginess", so I did. I like it that way. It's about the most bulged example I've seen, but oh well.
On the feet, your two points are both spot on. I could fix the knee on the ones I have, but maybe I should start a new set that's a bit taller.
I was also concerned that the case is not as wide as the original. The two photos are pretty close to the same angle, and perhaps do not indicate a strong deviation, but it sure feels narrower when looked at straight on. No matter what, it'll be a fine piece when done and in my front room. I lose a lot of sleep (figuratively) over things like this. Putting this much work and money into a piece of furniture makes one wish for a high degree of confidence in the outcome, which is not always available.
Coming back to the topic of this thread: Getting pieces just right from oblique photos is difficult, and you often can't tell how close you are until you've got the piece finished.
P.S. Thanks to Mike Holden, who generously showed me how to compress pictures with IrfanView.
