What do you think? Based on the 14" bell I'm saying tuba.

'at's no euph/bari! maybe even a BBb?

Wonder how hard it would be, to create a tool to do this analysis? The low tech analogue version is some string, laid out along the tubing path on a picture of the tuba; compare it to the height dimension for reference, and do the arithmetic to get the length, which roughly implies pitch.

I think runners and the like already have something like this in the digital realm, where they plot routes on maps. If there's a version where you can supply your own map as an image, that would be a pretty good start.

I think I would leave perspective correction issues unsolved. In the present case it looks like a modest rotation would do it, but more often there's serious foreshortening (due to close viewpoint/wide angle of view) that would be harder to deal with.

(just by eyeball, I get 11 feet. Oh, well.)

I have very little doubt. It's an Eb tuba.

Look at the 2nd valve tuning slide. If the end is about 4" from the valve its an eefer, about 6" its a BBb.

So, I need to cast more than one vote,

It's an Eb POS and I don't care!!

That would be an interesting experiment. Working from just pictures would be tricky, but if there was (or we created) a table giving approximate length of the straight lengths of tubing on 1st, 2nd and 3rd valves. Then it might be possible to make an informed guess.

Might be worth setting up some pictures of instruments of known size and only give a bell diamter or height measurment, and let reader take a shot at identifiying them.
