I've found a very interesting lot couple days ago - recovery set for IBM PC Series. Moreover, it's recovery for "Select-a-System" configurations (dual-boot with Windows 3.1 and OS/2 Warp).
What a pity that I can not buy to share images that disks with the needy ones since it can be shipped only within US.
Lot is here: https://www.ebay.com/itm/Reduced-IBM-Select-A … sk/292886911965
