I wanted to ask if you guys think the column shift arm for my '53 3100 is original and correct. Please check out the video I made in this and let me know. Thanks!

From what can be seen, it looks original, and, well worn at the joints.

Thanks for the feedback. Is there something I do to help with the worn joints?

Worn joints.
It all depends on how much slop there is, how well it shifts. If there is slop or sticking, you will probably have rotational shaft "bushing" wear and you will have pivot point wear. Some of it may be pot metal (hard to add metal to fix, hard to weld) and some will be rods/levers that may have wallowed out/elongated holes. These holes can be welded and redrilled, bushings replaced and the worn rods replaced/welded. There may be shafts to re-new also.
There are a number of mechanical features involved all the way to the tranny levers. A little wear in each can add up to substantial lost movement or wiggleization. Observation will tell you what to do. I don't know if there are any bearings or not. If there are, that's another fix point.

You know, as far as originality is concerned, that domed top to the shifter looks different from the one on my '49. I agree with bartamos in that each 'slop' of every joint is an addition problem, the whole is equal to the sum of all the slops. I replaced the rods with one's I fashioned myself using heim joints that attach to the shifter arms at the transmission. I have very positive shifts and ended up decreasing the throw which makes driving the 3 on the tree very pleasurable.

By fashioning my own rods I did away with the 'bell crank' pivot on the side of the bell housing. In doing so I eliminated three points of slop.

Looks like either a shift arm from a car or a Task Force. Knowing how GM didn't change much in mechanical design over many years as a general rule, I doubt that your shift arm is an issue.
