This was posted on Ken Smith's website several years ago:
Has anyone here ever seen a Bass by Calvin Baker? There is one pictured in the Elgar book and looks like a German Gamba design.
C.Baker trained and/or worked with Asa White. I have seen a Bass that was by Asa White the same day I dropped off my Mystery Bass at Biase's almost 4 years ago and only vaguely remember the Bass. It was a small 3/4 or 5/8 and had a dark varnish and a Flatback.
I have mentioned before that the Scroll on the 'White Bass although smaller to match the Bass was nearly identical to my Scroll which is on a full sized Bass.
Although my Bass has some English features as well as an early French style outline, American has also been guessed on it several times but with no match other than the White Scroll and by the way, the FFs on the C.Baker Bass which look close.
One of the reasons I never considered New England as a real possibility was became I have never seen an American Bass as European looking as mine. The thing to know here is that the Boston and NY school of Violin makers were mainly European immigrants that trained in Violin making before coming to USA. Both Asa and Jay White though were trained by their father John who made about 12 or so violins and is noted as the first Violin Maker in Boston but an amateur. Jay and Asa are I think credited as being the first professional makers in that area. The Gemunder Bros. George and August came later. George from France and August from German. Both initially trained by their father in Germany. George also worked for Vuillaume before coming to USA.
One thing that concerns me is that many of the Basses in the Elgar book are falsely listed. He accepted pictures in the mail with any named attribution and published it as fact. The 5-String Gagliano Bass is actually an English Bass and has been sold at least twice since as an English Panormo by one of the sons. One of the large d'Salo Basses listed that's in a Canadian Museum is old Brescian but not d'Salo.
