Circa 1974 Tokai made SIGMA electric?

Interesting that this giutar has both logos.
Apparently 1978 was when the transition was made from the Sigma Greek symbol to the Martin type script?
Still has a TRC on the headstock

One of my old guitars with the same label, Sigma logo on the headstock, but no TRC
No idea where this one fits in the timeline. 1979? 1979?
It's possible that there were different mfrs since this transition is not a smooth one? (New logo with the TRC and old logo without the TRC)
The snowflake markers, etc. are higher end than the 52SDR7S. Possibly different factory or production line.

Interesting 52SDR-7S
Circa 1976 ?
Has a TRC
52 = ?
S = scalloped bracing
D = dreadnought
R = rosewood (looks like curly mahogany...)
7 = overall grade
S = sunburst

The ones with this label, Sigma Martin USA, are solid back & sides from my experience.
I had a couple of them years ago.
I believe they came designated as a DR35N or DR28N
Pieces cut in Japan, assembled in the US like a Shenandoah.

That's a newer Chinese build. 2019 ?
Makes it confusing that these newer Sigmas are using the old 1970s logos.
Note these other 1974 Tokai built acoustics for comparison.
1974 DR7
Friend has acquired a Tokai acoustic. I would like help identifying it.
and this 1974 Hummingbird.

The back and sides of this guitar are laminated figured Ovangkol I think. This was used by Japanese builders such Yamaki who made the Japanese Washburns as a less expensive substitute for rosewood although it is a fine tone wood in it's own right.

No idea what this is (where and when made).
Something else for the Japanese domestic market?

I'm not sure what is up with these?
They are putting torches on everything, even a D18 copy.
I have to wonder if these are made in China under license from Martin??
CF Martin logo tuners on this one and the one above it.
