KA41-A MicroVAX 3100 / M10 or M20 (depends on box usually)
KA41-B ?? don't know this one
KA41-D MicroVAX 3100 / M10e or M20e (also box dependent)

KA41-E ?? This one I don't know

KA42-A VAXStation 3100 / M48
KA42-B VAXStation 3100 / M48

KA43-A VAXStation 3100 / M76

KA45-B MicroVAX 3100 /M40

The definitive list is of course the DEC (Compaq) MicroVAX configuration
handbook. There is no so much difference between a VAXStation and a
MicroVAX as you might imagine. Generally the former came with a Color
graphics card and the latter had only on-board video and it was disabled in
favor of the serial port console. Further, differences such as the box size
(tall vs short) often were different models (M10 vs M20) but otherwise they
were identical.

The bottom line is, are you trying to figure out how to write up your Ebay
descriptions or just figuring out what you have? The larger number is a
faster VAX and your fastest appears to be the M40.

P.S. What is a "chinese copy" ?
