Hi Tracy,
The dicing or checkering along the screw-off cap/lid of my oiler runs in only one (1) direction. The original ones have the DWM dicing pattern of lines cut in two (2) opposite, intersecting directions that form the "dice" or "diamond" patterns formed by the intersecting cut lines.
I paid $ 75 for my repro at a past Reno gun show which is a well-done piece. I keep going after originals on e-Bay...but get out-bid at the last minute and I am too cheap to go above $ 150 for these...
