Hi. I hope I can contribute to conversation. I was just at Trustys website and found a closed case back po 42 with no happy feet, ar, and correct according to the site he position. I am not knowledgeable enough to say that this is accurate per old specs but it is nice. So if you change your mind and want a closed back model they do have it.
For what it is worth, I just got a delivery today from Trusty. Under two weeks time, excellent communication and a beautiful time piece. I will discusss it in the appropriate forum. But trusty delivers the goods.
