I've seen comments that say it was a B&S/VMI stencil brand, and others imply it was a separate company that was eventually pulled under that umbrella. I was hoping to find a VMI serial number on the receiver, but all the receiver says is "Made in W. Germany". So I'm wondering if this is old enough to be pre-VMI.
It's a little shorter than a 186, and the bore is very slightly smaller (sorry, I have a tool sufficient to tell me only that much, but not an actual number). E in the staff is slightly flat, but overall intonation is nice.
Here's the only branding on it:
The keys have been completely replaced, the bar they're mounted on is probably not original, and the bar is in a completely different place (there are solder patches on the tubing where the old one was replaced), so there's no serial number on the bar.
There is a number on one valve: 446 or 977, maybe.
Do these slots in the valve actuators mean that it originally had S links?
There's also a pronounced keel.
Anyway, it doesn't look like I can just send a serial number to a B&S expert to check, and I'd love to get at least an estimate of its age, if not some more information about where it came from.
Before I forget: it has a really lovely sound, even when it's me playing it. And it feels very easy and ... direct, maybe, like you're really close to the horn. Sounds good soft, too.
