I have seen this huge bass (116cm s.l., 45.66") on-line many times and it's listed as an old English bass played in the Finnish Radio Symphony. A few weeks ago I noticed the small ebony arrows inlaid in the upper gamba bout corners of the Top. The only maker I know of that does that is Josef Rieger of Mittenwald (19c.). Rufus Reid has a bass by him as well. This one has a lion head as well.
