New guy on list with question

[Ohmymywldthg]

Hello everybody from Mark W. in Silverton, OR. USA I got a question and a
need I have bought a Pentax angle finder of about the spotmatic generation it
works great but I can't figure out the focus? My eyes seem to compensate for
where ever I turn it. If any body on the list knows of a site with the manual
for this finder or would have one and could send me a scan I would be
eternally grateful and you could have my first born (by the way he's 16 and
wants to drive LOL)
