No, it is not original. It had a lower profile rack and pinion.

A helical is operated by twisting the locked eyepiece clockwise or counterclockwise to achieve focus.
Most people who owned helicals bought them because they were the only ultra low profile focuser offered at that time.
They are great for fine focusing.
But in my opinion, they are more of a pain than a pleasure to use.

Edit: On second look it appears the adapter is there.

Heres the focuser that the smaller focuser fit into, is this one the original?
It looks to me like someone replaced the original rack and pinion with a helical focuser and then modified some sort of small refractor focuser so it fit the helical focuser. The stock focusers on older scopes like yours tend to be quite tall so that scheme may work.
Have you tried it with an eyepiece to see if it comes to focus?

The big problem with this particular 2" helical focuser was it became very loose and "wobbly" when screwed out too far ... hence the need for fitting another focuser inside it and then leaving the helical focuser screwed in all the way. Actually a rather clever solution by the previous owner.

I paid only $100 for this. I think I'll keep it for awhile!
