I tried to find soviet CLCC chips about the year... and finally I have done it
They are smaller than I expected.
Aren't they lovely?

KH1811BM1=DC302F DEC
KH1811BY1=DC303A
KH1811BY2=DC303D
KH1811BY3=DC303

KM1804BC1=Am2901 (usual DIP40 for scale)

And I have great doubt now... please help me.
One of KH1811BM1 is undoubtedly remarked.
It is very interesting to me, what is under layer of paint?
But I am afraid to damage so nice chip for nothing...
To be or not to be?

P.S. Please do not PM offers to me. Great soviet CPUs trade/sale coming soon. Thanks!
But if you have any question about soviet chips - PM to me. I'll be glad to help

These kinds of chips are usually soldered on soviet DIP PDP-11 MCM's. I love soviet chips! lol.

OK.
And what do you suggest me to do (or not to do) whis re-marked chip?

In my opinion, if the chip is named as KH1811BM1, that's because it's now a KH1811BM1. No reason to remove the layer You have a relabeled KH1811BM1 in your collection and that's all. Moreover, usually relabelled chips are rarest that others!
