Eldon,
I cannot tell by your photos of the grade. The "E" is for ejectors so that is easy to confirm. A C grade will have birds engraved on the sides of the receiver. The checkering pattern looks like a C grade.
At first glance the wood looks great.
I can't judge the wood to metal fit, ie is this wood a restock?
Are the barrels tight on the action?
Are the bores smoth and shiney?
Are the barrels thick enough, ie have not been honed or reamed to be too thin? See this thread:

Are there any cracks in the wood?
If everything checks out an A grade with that wood would be a great buy at $1500! A CE in very good condition sells for $3000 to $4000.
