Hi Gene,
Yes definitely; something that would be kept through more than one generation .
It could have seen service in more than one capacity .

I wonder how many scratched noses were inflicted by those shutters when the instrument was hastily put to eye .

Possibly for frequent use they were a nuisance .

edit:
Well, I just finished the cleaning and reassembly; tried it out and it's incredible .
Seriously, the depth of field is just incredible !
I understand the scribed line now; the actual focus range is an inch or so of slide on the draw .

I'll have to try stargazing on a clear night .

BTW, Is there an echo in here ??
