@ETMO It has been a long time! In this particular case, an exact reproduction is desired, so off the shelf is unlikely. I suspect the originals were castings. That approach appeals to me, although I’m not the one who is going to do the work. I’m just helping research ideas. I agree that years have removed the crispness. I think the original could be carefully cleaned, a cast taken, and then a plaster positive could be made. The plaster could be refined with dental tools, bondo, durham’s, and pixie dust…whatever it takes to build up what is missing and sharpen what is dull. Now, take another negative and work from that.
