Those look to be the old style warts. There were several different production runs of the “old style” wart though. Those look to be the latter of the old style. Most of the ones that the boys on the trail are use are from the black label production runs. The colors you have were VERY mass produced as the wart became real popular during the later production run. If you take a look on ebay you can see a lot of the older productions runs. The labels on the box will date the production.
Hope this helps! (By the way, I’m originally from SW MO where the wart is an AWESOME bait. I’ve yet to fine the success on the wiggle wart of here, but that doesn’t mean anything. ;o) The Mag Wart has worked pretty well for me here.)
Thanks,
