I do not know what you mean by a "non Lima Shay" plate. Do you mean a copy of a Lima Shay plate.
Be aware that all copies of builder's plates are NOT always smaller in dimension than the originals. I have a foundry that makes plates for me for engines we are restoring and the process they used turn out plates that are the exact same size as the originals.
There are many ways to spot fake plates, you need to know that the size of the plate is not necessarily a litmus test.
We covered the origins of these 2 plates over at RYPN.
