Would You Use This Crank?

I am building a 3V stroker and the kit arrived last week. The crankshaft is a disappointment to say the least. No specs or paperwork of any kind came with the part. The was some very light corrosion and/or residue on most of the journals. Lastly, as a result of balancing there were six deep holes in the front counterweight (two of which were filled???) and 4 deep holes in the rear. The crank is cast steel, so not super expensive compared to a forged one, but this isn't what I was expecting.

Is this par for the course or did I get hosed?......pics attached

(two of which were filled???)

Most likely filled with Mallory, a heavy metal used in balancing cranks.
But journals are not the prettiest I've seen.

I cant tell much from pics .
Get a second opinion from another machinist before doing anything else.

So the machinist said the journals have some superficial damage from the balancing. Getting the crank dunked and journals polished. I will probably have them check the balance just to be on the safe side. Thanks for the feedback
