M42 and specialty lens collection

Clearing out my vintage M42 and specialty lens collection, used on a Canon EOS 5D Mark II. This lot features classic retro lenses and high-quality adapters, including a very rare Carl Zeiss Jena matching lens and filter set, the famous Rubinar mirror lens, and the pin-sharp Industar macro. Great for vintage rendering on modern Canon DSLR or mirrorless cameras. 

NOTE: COLLECTION ONLY FROM KILKENNY. Cash or Revolut upon inspection only. For a serious buyer purchasing the entire collection as a single lot, I can arrange to meet halfway within a 40-50 km radius of Kilkenny (e.g., Carlow, Waterford, Portlaoise, etc.) to facilitate the handover. 

COMMUNICATION & PHOTOS:
Due to the volume of items, I have uploaded group photos of this vintage collection. Please feel free to ask any questions or request specific details here in the public comments section. I am happy to add more close-up photos directly to this listing upon request. Written communication via Adverts messages only to avoid any language barriers.
