Chris, I just had the router lift delivered yesterday. I purchased mine off Amazon from a company called Viking Mountain Tool Works, or something like that, it was the most economical place on the internet I could find this unit. I'm not sure if this was "new old stock" but the box appeared to be like it had been sitting on a shelf for a while. This thing is stunningly beautiful and aside of all of the complaints about incomplete fasteners and leveling screws on Amazon, mine had everything in the box including three of the red table inserts, crank and insert wrench. I assume when you speak of a "router plate" you mean the main
9 1/4"x11" 3/4"x3/8" black anodized plate and not the red table inserts. Mine does have milling marks in a regular pattern over the entire top that appear to be there from the manufacturing process. The black finish is applied on top of this. I wouldn't consider this a deburring proceess as I would think that would occur around the perimeter top and bottom of the plate, similar to the way a machinist would debur the edges of a part. I did read one review on Amazon where a purchaser complained about these machining marks "steering" his work piece around, but other's comments basically debunked the guy's review.
I didn't know we had to accumulate points here to post pictures, I know I can because this is only my first post. Thanks for the info.
Hope this helps,
