The seller says it is 1922 ....the serial is 34529Lyric is a stencil of a Martin Indiana. Having bell keys on the sides makes this one 40's or newer.
In the US this horn would sell for $400-500 needing an overhaul. There was a minty one or Reverb a few months ago that sat for a long time at $500. It also needed an overhaul. The problem with these is that if you can't do the work yourself, you would end up with a horn that is worth under 900 fully overhauled. I think they are very good horns. If you plan on playing it and keeping it, go for it.
