Bob, I'm glad you are writing. History is lost if not written down. By the time a third party account is told "he said, she said..." the truth starts to bend. You can help lock in that truth with your stories.
I think you made a good choice waiting to marry and do it right. You'll notice that's what a lot of the youth are doing today now. I have been married 34 years, have three kids, a son 33, daughter 34, daughter 26. None show any inkling to getting married. But seem happy. Perhaps your friend Bill put the "Old Maids Dream" on this one just messing around with everyone...or even you! I'm glad to hear you saw it in his shop, so he did build it?
I've been enjoying cleaning and inspecting this rifle this morning. Can't get the nipple off yet, but I got the "C. Baker" shade tube off. No other marks on the barrel. The sights are very sharp and square. The rear notch is very deep, just a straight cut line from the top, about 1/4". Seems like they will work fine on targets.
The bore is pretty smooth, some flash rust but I may just shoot it off. Towards the bottom there is a rough spot I can feel, doesn't feel too bad. Towards the front, I can feel a choke get tighter. It's 8 lands, somewhat narrow, but not like a Pope.
The lock is indeed a Robbins, the signature was hidden behind the main spring.
I may get some caps and balls out this morning and go shoot a couple rounds, in honor of you and your friend Bill!
