To anyone else needing a high fidelity reproduction of an original brass Mori-Seiki gearbox tag for the 32-1800RPM Imperial layout plates, I have six on the shelf from the most recent etching run, ready to ship. Cost is $115 + $14 shipping within the U.S. via USPS Priority tube mailer due to the size of these plates. Total of $129 delivered, you drill mounting holes to match your factory plate for a perfect fit.
If it works out that Gyzmo's metric version is not prohibitively expensive to replicate with new artwork, I will update the thread when that design is available to purchase.
Thanks!
