These are two bullseye lenses in their brass mounts and various other items relating to microscopes. I am sure the would-be collector will know what these items are and what they are used for. The two lenses are a different colour brass to the two stands so they do not belong to each other - even the threads are different. One lens measures 1 7/8" overall diameter and the other measures just over 2". We have been sorting out the family home and came across a large container with microscopes and accessories and other scientific items - I am selling all these on ebay. Maybe these items are just useful spares to you. These items together are all fairly heavy - not far off 1kg without any packaging so I would send them by First Class Recorded Delivery which will be approximately £6.50.
Anyway, nothing else I can really say - I think the best way is to look at my photos as these items are out of my field really. There are seven items in total and I am sure some of them may be of use to you.
I do not charge for any packaging - just the Royal Mail postage cost to you. If you require postage costs for overseas please email me.
