Hi again lovemygreen, and thanks for posting the pics.
Overall, it seems to be in good condition.

Some things I have observed:
The grass deflector is installed incorrectly...on side is hooked under the catcher attachment lug. Just release the other side and straighten it up.
I also would like to see a pic of the bent blade....one of the chains and all sprockets (especially the small top primary chain sprocket). These are located in the chain case on the left hand side of the machine. Just remove the cover.
Please take a pic where the sprocket is
not covered by the chain...so as we can see the teeth.

Finally, the complete string of the long series of numbers stamped on the cooling air cowl of the Briggs. They will be grouped into Model, Type, and Code. We can then tell the date of manufacture of the engine.
As for price...$500 -$700 is about right and $100+ for a spin grind. The engineer will be able to straighten the blade if it is not damaged beyond limits.
