Spencer receiver dimensions

[trenches]

I was asked by a member to post Spencer receiver dimensions.
So this will be the thread.
I'll do that sometime this week.
In the mean time here is a picture of the rifle so far.
BTW, I made the barrel from a GM barrel blank. And turned the square threads. Which are 1.0"x10tpi.
There's your first dimension.
I'll get more.

Sorry for the delay. My old computer quit working and I had to get a new one. So I lost some data which I am re-acquiring.
I have a drawing made with most of the dimensions on it. Most of them. Will try to get a picture of the drawing up as soon as I figure out the method of getting one on my computer.
What I can do if someone other than the guy who requested it wants one is make a copy and send it to that person.
