Lovely percussion Vierling(or is it 5 tubes?( fnf ) as I seem to see 5 nipples) peddled by Anton Vincenz Lebeda.

Forgive the grainy image a result of a quick image, but fuhrmann had forwarded me some very interesting info and hopefully he'll comment on the stepped lock sporting arm,which I'd say rivals anything from the period including any wares by the craftsmen on the little Briish Isles. fuhrmann may be spot on with Anton Vinzenz Lebeda being responsible for the stepped locks.

Kind Regards,

Raimey
