stampcrow - are you looking for an image of a stamp transfer roll or specifically of the transfer roll for the 3 cent 57? There is a transfer roll here - https://invertedjenny.com/production
(about half-way down the page). As far as I know, there are no images of the transfer roll for the 3 cent '51 (or any of the very early US Stamps). There are some illustrations of what the transfer roll might have looked like in the USPCS 1851 sesquicentennial book and the Frajola / Mayer 5 cent book, and probably other places.
