Identifing a Koetsu cartridge.

I have two Koetsu cartridges that came with a system I bought. They are around 20-25 years old. The box of one is penciled Rosewood Signature #13275 and the other is also rosewood, but has SCWA #015 penciled on the box. The distinguishing feature is that the screw slot is angled like the tiger eye. Anyone have any idea what model it is?

Do not worry about it! You have a real classic!

If it is is good shape, you will get the "true" original warm sound that the "old man" put into it.

That classic sound is lacking into today's Koetsu cartridges, IMO.

Just found this thread. Would like to understand better the response, wich one is oldest?
