Not having seen your machine, it could be either German or Japanese.
Belvedere was one of two outfits representing the German Adler company
in the US in the 1950's and '60's. They sold a few different German-
made machines with Adler labels. When Adler stopped making domestic
machines, Belvedere kept on selling Japanese machines. Some were
branded 'Belvedere Adler' and many of these were made by Riccar. In
Germany, Adler also marketed some of the same machines but with the
label 'Riccar Adler.' US sales versions typically had the same
colors as the Riccar machines being sold here, while in Germany they
all seem to have been painted gray before being sold.
I think maybe the Belevedere folks also sold some machines as Adlers
that had no counterpart in Germany. I don't know what rights they may
have had to the Adler name.
In general the earlier Riccar machines seem to have been rather
decent: heavy, all metal, well-machined, and pretty well balanced for
that time. I use one for canvas work quite routinely, with an
oversized balance wheel. There were zig-zags versions with and
without cams, and at least one version of a HA-1/Class 15 straight
stitch machine. One of the earlier cam versions had a single
two-sided cam, accessed from the back; turn it over to get more
IF your machine is in fact a Riccar it will probably sport the letters
JA-3 somewhere below decks. And if it is, you can search for a manual
for the original Riccar version here:
If your machine has zig-zag features, try the sewing machine listing
for the RZ-104b, etc., or snoop around.
