Odd Duck Foundry of Orrington, Maine, has undertaken the creation of a replacement builder's plate for 470. This is the master match-plate from which the plate replacements will be cast. The plates for the locomotive will be cast in iron, whereas copies will be made available for sale in aluminum, if interest is expressed. 470's original builders plate were lost during her service years when enlarged steam delivery pipes were applied to the locomotive. The new pipes overlapped the location of the builder's plates and they were either discarded or damaged and removed. Sister 469 had similar damage to its builders plates and wore them in damaged condition until she was scrapped. This plate is modeled upon an original rubbing of 469's plate, which is privately owned and made available to New England Steam.
