"BRF Is there any external indication between the 7000 and 7000 m2?"
No, the Mk1 and Mk2 look identical with no external differences. EAD did not silk screen Series II on the faceplate as they did with late production Series III. Many of the original Series 1 were sold with the gold faceplate. Upgraded Series 2 to 3, and early production series 3, have a HDCD badge placed over the de-emphasis indicator light (which now denotes HDCD disc). Late production series 3 had HDCD silk screened and series III on the faceplate.
