Attached is a drawing from one of your photos. I had the most difficulty with the legs, even though I measured carefully and dropped plumb lines. The main problem was getting the legs in the right place.
I like to add that I find scanning the drawing gets better results than taking photos. The result is closer to the contrast and brightness of the drawing, but still not the same. It’s a bit disappointing after trying carefully to match the values.
Thanks for your feedback,
