I could find no information about the composer which is a pity because this is a very well written composition. There are a number of popular tunes of the day cleverly incorporated into the piece including Marching to Georgia (see the trio) and it is well worth a listen. I could speculate that Weinstein could be a pseudonym for one of the more well known composers as I could find no other music attributed to him. The score and midi are in the library...Steve.
