I need to recover a set of document files that were backed up in June 1995 using the native BACKUP utility in either DOS 5/6 or perhaps the backup utility in Windows 3.1. 

I do not know the brand (e.g., MSDOS or DRDOS, etc.) or the percise version of DOS was used to make the backup.  The 3.5" floppies that I have includes two files (one each disc): cc50625a.001 (1,424 kb) & cc50625a.002 (1,424 kb); I have these files backed up on hard drive.

I have limited time and resources to try to find the right solution to "unlock" and extract the files.  I am hoping that someone has the knowledge to help.  I'd be willing to pay up to $40 to anyone (VIA PayPal) that can extract the files.Are you sure its just 2 disks? USUALLY in a spanned backup you have the last disk with contents smaller than the maximum storage capacity; such as 3 disks where disk 1 and disk 2 are maximum capacity and disk 3 is say 780k of 1.44MB

Most utilities that I know of require the full backup set to retrieve a single file even if the single file resided on disk 1 and there are 3 disks. It assembles the spanned data and decompresses it to readable file and folder contents.

Due to legal reasons dealing with unknown data origin, many will AVOID getting directly involved in doing the work for you here. Here we offer help and advice and you take the knowledge and code etc that we provide and you have to take that and edit if needed and execute it on your own. You might be able to bring the disks to a computer shop and have them check them out. They are probably too old to have Metadata to give insight as to what they were created with to then know how to expand them, however you could right-click on the backup files and select properties and then summary to see if they have metadata. I am pretty sure 1995 pre-dates metadata info associated with files though.
