Just found this .. out of date but interesting. Also describes a hybrid (spruce top) rather than lammy bass.
"Its coming to the end of the sale of my Vintage 1930's Artia Excelsior Double Bass (¾ size) - on ebay I'm afraid. If you are interested in it get your bids in now otherwise it will go to someone else!

Here is the description I have put with it (through a bit of research on the instrument along with previous sales of the same model elsewhere:
"The beautiful rounded tone of this classic instrument is superb. One of the 'Excelsior' range by Artia as a special commission to the Boosey & Hawkes company, these beauties are not made anymore and are extremely rare. Made circa 1930, this contrabass (or double bass) with good quality bow is in good condition for its age. Soft-padded zip-up case with pockets for bow and spare strings, resin etc. included.
Some specifications:
Solid spruce top
Grain is nice and the colour, a classical oil varnish.
Ebonised fingerboard
Maple wood is used in the construction of the back, the neck and the back ribs.
This really is a lovely instrument which has a deep, rich tone for both classical and jazz playing. 3/4 size (just over 6ft) with a great action and feel. Woodwork has evidence of use with scratches (which some prefer), but if you prefer the new look, it will cost next to nothing to add a layer of varnish. Neck in very good condition, and all nuts 'n' bolts in good working order."
Hmm.
