Niche Supplier for Thin, Flexible Spindle Sander Sleeves (Vintage Tools)

Users of older or less common oscillating spindle sanders encounter difficulty sourcing specific replacement sandpaper sleeves (e.g., 1 1/2" x 9", thin, flexible, cloth-backed) that fit their tools. This indicates a niche market opportunity for a specialized supplier or manufacturer to produce and stock these uncommon sizes and material types, catering to hobbyists and professionals who maintain vintage or unique woodworking machinery.
