The RGX 520 Models

There are distinct runs of these the first in 1986 and 1987 comprising domestic made in Japan models The 520J, The 520P and the 520R. The second in western catalogues the 520FZ and the 520 DZ from 2005 to 2007. There is also an FZR which I don't have full information on.

The 520DZ, 520FZ and 520FZR

These appear in the Western Catalogues from 2005 to 2007. I don't have access to any Japanese catalogues after 2001 so I can't say whether or not they were available to the domestic market. They are both made in Taiwan or Indonesia. What I know about the FZR is that it appears by serial numbers to be made in Indonesia around 2015 but I can't find it in any catalogues.

The 521s

There are 2 (or 4) models there is the 521 with a Maple Neck Version and a 521D also with a Maple Neck Version. The 521 is in the western catalogues in the early 90s and the D appears in the Japanese catalogues in the mid to late 90s.

The 521D
This along with the DM appears to have been for the domestic market but was made in Taiwan.
