It been a while since I watched those videos and I forgot Scott had used a clone Jig Saw.
For clarification the later version of the A-34 Jig Saw is shown below. The easy way to tell this later version from the early version is the partial belt cover.

For reference the early version of the A-34 Jig Saw is shown below. There is no partial belt cover.

As I said before there is very little difference between the two versions which are the Lower Frame Assembly, Drive Housing Cover and the number of screws to hold the cover on. I have both versions but prefer the later version for use. This is not just because it is a bit safer having the partial belt cover but is actually the difference between the construction of the Lower Frame Assembly. The Lower Frame Assembly in the early version is open throughout and saw dust can get into the gear box. I have found saw dust in the gear box of all 3 of the early version A-34 Jig Saw I have restored. The later version corrected this by closing the gear box off from the rest of the frame.
The biggest difference between the A-34 Jig Saw and the Magna/Shopsmith Model 610 Jig Saw made after the introduction of the Mark 5 is the A-34 uses the Model 10E or 10ER table while the Model 610 Jig Saw is a more complete unit only needing a power source.
The Model 610 Jig Saw is shown below for comparison. This Jig Saw has either the "Greenie", "Goldie" or gray paint scheme depending on when it was made. A "Greenie" painted one I restored is shown.
