It would be difficult for a regular person to tell them apart, if you don't know the differences so some people could be easily fooled.There are a number of small differences in how the frame is built. You can also tell by weight and general feel of one.
Along with the serial number which is visible on this one which is the easiest way.
There is no way that someone can tell a polished pantera and a polished Zaskar apart of the same level of polishing is done to both. At the end of the day it’s just polished alloy and the grade or whether it’s been painted prior has no bearing.
And I am happy to admit I don't know everything either. I am learning though. Only if you just had the frames side by side in hand could you tell the difference in weight and feel, you can't tell from a photo (from a lay person point of view).
