Carl Zeiss Asembi 15x 30x 50x. These 110mm Asembi's are, I believe, from around 1928. The serial number is 12317. They're marked Car Zeiss Jena D. I have had to list this as "for parts or not working" because a part is missing.However most of it is working, please read on. The binoculars need an overhaul, one of the 50x occular lenses is missing, there's a couple of screws which need replacing, and there's quite a few areas where the black leatherette is missing. All the lenses need cleaning.
The two elements which compose the left objective lens (standing in front of the binoculars) are becoming un-cemented around the edge. You can see this on the left side of the lens in photo No11. This un-cementing is, as far as I know, repairable at no great cost. This picture also shows that both lenses need cleaning.Still on the same photo, there's some sort of ring inside the hood of the right lens - the one on the left side is missing. It doesn't look like it does very much. Two flaps which would cover the lenses when not in use are missing, the hinges remain. One of the 4 screws which secure the right hand viewing assembly to the main body of the binoculars is missing - see photo No9. Also one of 3 small internal screws (not visible in any photo) which secure the rotating part of the right hand turret assembly is missing. This missing screw causes some play in the 3 lens assembly and affects the collimation. If you hold the (right hand) ocular to the left and up with a little pressure the collimation becomes correct at the 15x magnification. At 30x magnification it still needs correction and, of course with only one ocular lens at 50x, I cannot ascertain the state of the collimation at this setting.
The missing screw needs replacing in the first instance. The images on both sides at 15x and 30 x are very good considering that the front lenses and the ocular lenses need cleaning. The 50x is truly exceptional, I saw a single thread that a spider had made at a distance of 85m but again all the surfaces need cleaning. The binoculars are missing the 50x ocular lens, you can see that in photos 8 and 9.
In photo No9 you can also see that the housing where the missing part should screw in, is slightly distorted (top edge). I haven't managed to find a replacement 50x ocular lens but a modern lens may provide a repair. The one in the photo No6 is a 20mm and does give an image similar to the existing 50x lens, but it would take a little working out to get it right. Then, in order to make it look authentic, you'd need to have somebody make a brass copy the existing 50x housing and mount the new lens in the new turned part.
If you could find the right lens, you might have only to do this on one side, i. The side which is missing it's lens, but if you couldn't find a match, you might do the above for both sides. The stand may well be an original Carl Zeiss part. The vertical part seems to have been chrome finish, now painted over in the matt black. The foot had a plaque attached but this is now missing so it's difficult to know who manufactured it.
If you do not want the stand, please let me know. For transport, the binoculars will have the turret assemblies removed from the main body of the binoculars. It only requires 7 screws (1 screw is missing as mentioned above) to be replaced in order to re-assemble the binoculars.They are 850mm long, depending on which ocular lens is lined up and they weigh 15 kilograms. Extras: I've tried to show the missing leatherette as much as possible in the photos but there's one area which doesn't show easily, that can be seen in photo No10, the binocular support which is pointing downwards, has at some time been folded upwards and you can just about see where it has touched the main tubed and affected the leatherette - small arrow.
In the same photo, the top arrow shows some leatherette missing from the lens hood. There's som much to describe that I hope you will take it upon yourself to ask as many questions as you need it in order to satisfy yourself. Depending on any prospective buyers feedback.
