Several members of the Schnitzer family have been active as instrument makers during the first half of the 16th century. Their instruments are marked with A or A A. This is one of the makers marks that is mentioned in Ganassi's la Fontegara.
The Schnitzer recorders work well with the fingerings mentioned by Ganassi. The instruments have a slightly narrower bore, a less conical bore, are a little longer and have bigger and lower placed holes than most other renaissance recorders.
My instruments are strongly based on originals by Schnitzer (and one or two similar instruments by other makers) and they work well as consort instruments with a few notes extra at the top as well as solo instruments.
These instruments are made in maplewood, their pitch is A=466Hz and they are tuned a light meantone.
