Carl Zeiss Vintage Carl Zeiss Jena Theodolite THEO 010 A Surveying Equipment

Doesn't have any identifying brand markings. From what I gathered from my research I believe it is the brand and model in title. However I could be totally off so any information is always appreciated to make a more accurate listing. All lens look in good shape no scratches or anything. Body shows some wear but no major flaw or anything visible damage. Both levels also seem to be working as they should.
