Something a little [lot] bit different!

OK, here's one to tickle your synapses and niggle your neurons... and hopefully you can give me an answer!

It's an old photo of a Yeti Airlines aircraft taking off. Just to make things interesting, the photographer managed to get the baggage in focus, but the aircraft [in the center of the frame no less!!] is well out of focus. No, I did not take the photo! :-)

The rear of the photograph had the inscription "Plane is taking off at Paphlu Airstrip near Katmandu" [sic]. The photo is undated, but is from several years ago.

It looks to me to be a DHC-6 Twin Otter, but clearly the registration is somewhat difficult to read. :-)

Can you provide any more details on this aircraft or the operations of Yeti Airlines? Current aircraft [according to their website] appears to be a Jetstream J41.
