Yes, based on the photos, that's a typical Tamaya-like sextant. Yet another brand! A few little details of interest:

• The scope is backwards. :) This is harmless, of course. The person who attached the telescope for photos presumably didn't know any better or just didn't notice. When the scope is turned around, you would discover that it could use a little rubber eye cap. I find these small scopes rather annoying in their normal state.
  
• Second, it's interesting to note that there's no vernier scale on the micrometer. This is actually a good thing, in my opinion. The vernier scale on most modern sextants is a pointless complication that confuses new navigators. The lack of the vernier may, however, provide a more specific date on the instrument, if there's no other reliable date available.
  
• This sextant also has a metal overhanging shade, like an umbrella, above the horizon mirror. I've never quite understood the supposed advantage of this "umbrella shade", and in some Tamayas that I have looked it, it tends to partially block the view through the sextant. If you decide to buy this instrument, you may want to remove the umbrella shade. This should be easy.
