It has a 16.25 inch scale.
Here it is next to a mandolin and a tenor ukulele.
Here it is next to a Filipino banduria, which has 14strings in 6 courses.
It reminds me a bit of the Puerto Rican cuatro (which I used to play when I lived there many years ago). They both have ten strings, but the cuatro has 5 courses, arranged in pairs. It too is rather small, but your tiple looks as though it's even smaller, judging from the proportions with the tuning gears.
Those irritated by grain of sand best avoid beach.

I bought a ten string Regal tiple, made in Chicago, at a yard sale a few years back. I haven't used it much till COVID locked me in and I started taking part in a weekly ukulele get together.
The tiple has 4 courses of strings and I tune them gG-cCc-eEe-AA. The saddle is not compensated, so playing far up the neck causes some sour notes, so I stick to the first 5 or 6 frets.
Any other tiplers on this site?
I'm not sure how to add a photo.
