Lone wolf I guess, as marking anything, Gas Globes etc really doesnt matter much either way I see. Any repo especially if it is exact or a perfect copy like T-Ways globes(no offense) will kill the interest of some people looking to buy an original. Most will settle for a repo marked or not to put on their pump vs. nothing at all.
Perfect Example: 1950s Double Bubble Glass clocks, pedal cars, serving trays and ice chest coolers took a dive after all the China repops came over. They are marked and dated but take away from the interest and pricing of the original ones...especially the common ones. A good reproduction Gas Globe with or without a date is no different. Dont get me wrong, New repop Gas Globes really top off a restored pump but what about someone holding the original globe hoping to sell it to the same person needing one for his pump. Its all about money.
