35mm film SLR camera, lenses, accessories (New Marston OX3)

Praktika MTL5 SLR 35mm film camera, M42 screw mount; Pentacon 50mm/f1.8 standard lens; Tamron 80-210mm/f4 zoom lens; Tamron 28mm/f2.8 wide-angle lens; 2x teleconverter; Hanimex TZ1 flash gun; case and assorted accessories. Not sure how well it still works: it's been sitting unused for 20 years, and there may be some mild lens fungus (https://en.wikipedia.org/wiki/Lens_fungus) on the lenses.
