Sentry Siren port ratios

[archizackture]

Sterlings were never 8/8 port. They only had 8 port Model "K" sirens.
The dual rotor Sterlings were either 8/16, 16/16, and I think 12/12 for the Little Giant.
Unless you custom ordered it to be 8/8, which I think no sterling vertical like that exists.

Actually there was supposedly an 8/8-port M-10 found by someone. I don't remember where it is, but a while ago I made a thread about the same thing and someone might have linked to it there. You should be able to search it.

Somebody had commented on a video I made of the 8/16 M-10 in my hometown, and they thought it sounded like it is 8/8. I considered it as a possibility for a while, hence why I started a thread about it, but dismissed the idea after listening at closer proximity and clearly hearing the higher octave.

Not to muddy the waters a bit, but wasn't there an 8/12 M-series found some time ago?
