This is a 6 inch Dobsonian mounted reflector. They are VERY simple to assemble-- only two parts-- the base and the tube. The small finder scope goes on top. The eyepiece goes into the focuser. That's it.
No manuals exist for that brand but all of them assemble and are used in the same fashion. Here is a manual for an Orion brand Dobsonian just like your scope.
Are you trying to get the front ring to attach to the front base? If so... clamp the ring onto a 1"dia. x ~12" long wooden dowel. Set the ring into the base from the side of the weapon (90^ from the barrel). Making sure the ring is fully seated onto the base, turn the ring/dowel 90^ until the dowel is parallel with the barrel. The fit is quite tight between ring and base. Do not put the ring on and take it back off again as the fit will deteriorate.
* IMPORTANT * Make absolutely certain both the front and rear rings are exactly in line with each other before mounting the scope. You do not want to bend or kink the scope. There are tools you can buy, or... use a 1" dowel in each ring. Align the ends of the rods with slight turning adjustments to the front ring to get both rings pointing the same direction. The rear ring does not turn, only the front one.
With Swift Binoculars the serial number contains the year of manufacture eg No. 1-662 Blah blah. The first two digits after the dash being 66 indicate the year as 1966. If it doesn't have a dash such as the late model Audubon then it is the first two digits of the serial number. eg.. 0745 blah blah would indicate 2007. Try this with your scope.
Hold the outer portion of the elevation knob and unscrew the screw on top. then pull up on the outer portion and you'll see a silver screw marked with an arrow and the word "Up". Sight the rifle at a known distance and then line up the knob with that distance as you push it down on the scope and replace the screw. I have one of these and figured this out on my own, however I'm missing the mount and would like some pictures and dimensions of the mount if any of you can get some. I'm gonna be machining a new one and would like to keep it as close to the original as possible.
I had the same problem but was able to solve it by shimming the scope mounts with a thin piece of plastic. Put it under the rear to raise the sighting and under the front to lower. I still plan to buy my son a better scope.
