Scanning movie film is essentially the same as scanning photo film. I've moved this to the photo forum.
Describe what you mean by "fragments" ... are the film cels complete, or have they been brittled and broken into cellulose shards?
Are the images B&W (likely), B&W with tinting or toning, or color? While less likely, color did exist in 1923.
If the images are damaged, the
Epson V500 should do an admirable job. We have
Epson V600 for document and print scanning.
The only better way to scan would be to use the pressed glass slide method, found in some older nuisance-to-use Minolta professional scanners.
Standard film scanners would be useless here, if the film is too damage to be run through sprocket-based loading.
