That does sound like a fun project. I don't know about plans, but
it would be an easy thing to make once you had the optics. About
what size would the objective (front) lens be? I'd guess they
were about an inch? If it was me, I'd start by looking for an
objective that fit the project, then size everything around it.
Perhaps one of these would do it:
They also have lens sets for making eyepieces, and they aren't
the only surplus optics shop around. The result would not exactly
be authentic, but nobody will ever know from the outside.
Then it is a matter of some nesting brass tubes, some felt (for
the joints) and some machined brass to hold the glass.
