I'm trying to determine if a crankshaft I found is actually for an 0290-D2 or not. The numbers stamped on it are: H8429, 6415D,W2-1, 61158-V and B-28 stamped in ink but none look like a valid part number according to my 0290 parts manual. Can anyone verify this is an 0290-D2 crank or if not, what it is off of?

You said the numbers are stamped into the crank. Are any of the numbers cast into the crank?

I think your best bet is to send it to someone like Aircraft Specialty Services to identify or measure everything IAW (in accordance with) the table of limits in the service manual. The manual also gives stroke I believe. I have never seen part numbers on the crank or many other internal engine parts.
The numbers are what the seller gave me. I am going to pass on purchasing the crank and other parts anyway because the crank flange has been ground down to .209 and is now too thin. My neighbor and I just bought a Hatz CB1 that has an O-290 D2 and I was going to start collecting parts to overhaul its motor.
