Getting ready to install the oil pan.
All the screws had flat washers under the lock washers when I took it off.
Was this done at the factory or has someone added them?

That is the way my 1936 car and truck are. I can tell when one was loosed and they used something else. New ones can still be bought. I would say yes to your question. Flat pan head type, straight slot, with lock washers.

thanks!
I'm surprised 88 people read this before someone answered.
I already put it back together Saturday night with the flat washers, I'm glad I do not have to take them off now......

The fact that 88 people read a post without responding is not unusual particularly when a question about what originally was done is involved. This is true when we are referencing 80+ year old vehicles that have surely had some modifications over the years. How can any of us be sure that someone didn't add the flat washers? Well I just checked a 1934 Chevrolet parts book and found the following listed under Oil Pan with Drain Screw:
Round Slotted Head Bolt (1/4" - 20x1/2")
Round Slotted Head Bolt (1/4" - 20x1")
Lockwasher (1/4")
Plain Washer (1/4")
Hex. Head Bolt (5/16" - 18x9/16")
Lockwasher (5/16")
So it looks like the screws along the sides of the oil pan did have a flat washer as well as lockwasher. However the hex bolts in the corners only had a lockwasher.
How Sweet the roar of a Chevy four!
