I don’t have the skills that Mr.Ford has at posting photos etc., so I just comment on what my opinion is after observing what already has been posted in this thread ( which is becoming a almost a library at this point:)
It’s still my opinion that the black man is more likely to be Carl Jones.
It’s curious that the WC investigators seem to have avoided a more rigorous interview with Jones and Lewis.
In that more recent interview of Lewis , near the end of it, a women questions why it appears that the black man in Altgens photo is looking towards Daltex building. Lewis looks at the screen and is not able to give any reason, , and he seems a bit confused.
Note: the abbreviation BDM will be used for “black doorman” to designate the black man whom is at the lower west side steps of TSBD and whom Is either Roy Lewis or Carl Jones.
The b&w Weigman film clips shows the pants and shirt of “black doorman” (BDM) being a very light tone of gray approaching almost as white as other shirts of other persons such as Sarah Stanton (fluffy shirt person raising both hands to shade her eyes).
In one sense, Mr. Mason, this has become a side-issue since the resolution of the Lovelady vs. LHO question in Hughes-Bell-Towner: the identity of the black man in front of Mr. Oswald does not have any bearing on the identity of Mr. Oswald. The critical issue is not Jones vs. Lewis but Lovelady vs. LHO.
However, it would be good to resolve the matter, not least because of its implications for the Altgens photograph. (To recap: I have argued that the 'investigating' authorities were desperate to obscure
what they thought was Mr. Oswald's Coke-holding right arm, and pasted in the face of the black man they
thought was just in front of him in the doorway; they found an aftermath profile image of him and used it.)
Now! Let's separate out the questions:
Q1. Is the black man in front of Mr. Oswald in Hughes Mr. Carl Edward Jones?
Q2. If he is NOT Mr. Jones, is he Mr. Roy Edward Lewis?Re. Q1:Here's Mr. Jones (or at least the man we all presume to be Mr. Carl Edward Jones) in a color photograph, with a person in white in his vicinity:

And here's the black man in front of Mr. Oswald in Hughes, with a person in white (Ms. Madie Reese) in
his vicinity:

I am perturbed by the two very different color stories being told in these respective images.
As it happens, Mr. Hughes has already filmed a man who looks & is dressed strikingly like our Mr. Carl Edward Jones----------walking south at Main-Houston shortly before the motorcade:

He offers a useful point of comparison. Not a hint of blue on the pre-motorcade man (other than his gloves). Can anyone make a gif of
this man in which his clothes show up in a shade of
blue?
On the other side, here's an aftermath image from Hughes of what appears to be our 'Mr. Jones' from later in the Hughes film. He's leaning against the street pole:

The color of his clothes is more metallic here. HOWEVER: just look at the color of the brown brickwork on the Depository----------very different to the more naturalistic tone of Mr. Hughes' pre-motorcade footage of the Depository front.
If all this can be resolved in favor of our Mr. Jones, then great. But I'm just not at all convinced at this point.
Re. Q2:I am honestly perturbed by the Bronson film footage of a man who looks (at least from behind) a ringer for the young man we see standing with our Mr. Jones in the aftermath images:


And, while the young man with our Mr. Jones does look quite like Mr. Roy Edward Lewis as shown in MUCH later images (photo in
No More Silence + recent conference appearance), I would caution against the
assumption that this young man is Mr. Lewis.
IF he is Mr. Lewis, and IF that is him in Bronson, then he was not in the doorway at the time of the assassination. This would offer an alternative explanation for his 'confused' recollection of where he went and what he saw in that doorway.
Which would leave us where exactly? Well, with a third possibility that is worth considering: the black man standing in front of Mr. Oswald in the doorway is NEITHER of the two black men
we have been taking to be Mr. Carl Edward Jones and Mr. Roy Edward Lewis.

What I do NOT question is that the face in profile we see in 'Canonical Altgens' is that of the man in cream clothing on the steps seen in aftermath images. I believe the 'investigating' authorities
assumed him to be the black man in front of Mr. Oswald in Wiegman, and took a profile image of him from one of the aftermath photos and pasted it in (with further retouching, e.g. of hair). His face is not in the Cronkite version of Altgens, the only (so I have argued) time the American public were shown the unaltered Altgens photograph.
Here are two profile shots of that man I have taken from two aftermath images. Either could have formed the basis of the profile face we see in post-Cronkite Altgens:
