Hi Trevor,
The term "German Quality" is now being used by some Chinese suppliers, so we need to be wary of some of those products. CIP1 seems to carry some of those products.
Regarding Kolbenschmidt main bearings, the few sets that I have left say: "Kolbenschmidt Germany" on the sticker, but they used to say "Made in West Germany" or "Made in Germany". I have a feeling that they are all made overseas. Mine say "quality guaranteed by Kolbenschmidt".
I guess the samba would be the best bet for NOS sets. Are you doing another restoration?
