Picked this up for £75. Everything was seized and it needed a hell of a clean and service, but all fixed up now after soaking overnight in a bucket of soapy water then scrubbing through everything thoroughly. Loads of crusty black crap came out of it! Previous owner had 3 felt washers on each valve stem (sending the valve alignment way out), valve 2 and 3 switched around, and a tenor horn mouthpiece! Surprisingly there's not a single dent on it, and the lacquer wear around the valves suggests it's been heavily used but taken care of at some point in it's life. Serial # is 710665 which by my reckoning dates it late '70s early '80s (?).
From what I can ascertain from what little info there is online, these were Czechoslovakian, designed by Josef Lidl, used standard Amati valve blocks with quality hand-built tubing, leadpipe and seamless bells. Has some neat features like 1st and 3rd slide triggers, nickel slides, a reverse leadpipe and an unusual bell rim that's folded over the wire further than usual. Feels very solid and well made. The valves are a little finicky but now they're working they feel good, if a little clunky. I think they'll be quite oil-hungry. Compression seems decent enough for a well-used instrument this age.
Haven't had a chance to give it a proper toot, will report back with how it plays.
Anyone know anything about these?
UPDATE: Gave this a blow with my trusty Warburton 3M, and I'm very impressed. This definitely plays like a pro horn, with a bright, fat and focussed sound with a little sizzle when you want it. Good intonation, and easy to dial in with the triggers. Feels like a large bore, needs lots of support up to top end but plays with a nice open tone up there - lots of power on tap. Tone is quite Strad-like, but a little brighter. I really like it. The valves have quite a long travel compared to my other horns, which takes a bit of getting used to but useful for slides/gliss. Pleasantly surprised, and definitely a keeper.
I used to own an Olds Super, and I reckon this plays better than that.
Now to find a suitable case for it.
