I have a Weidlich matchstick filler from 1906, I know because that is when it was given to Margaret. It is black hard rubber with gold filigree. The filigree has shallow linear designs. On Anderson Pen's blog a Weidlich matchstick filler with a bit more relief was discussed in a 'favorite pen' video. That pen had a more ornate filigree, more relief. Now on eBay there is a Weidlich matchstick filler with a gold overlay in high relief, beautiful.

My question is, would Weidlich have jobbed out the overlay or filigree and had the various types in a catalog that the purchaser could specify or did the purchaser send their pen to someone who specialized in making the filigree or overlay themselves after purchase? Did some of the pen makers have in-house artisans that did the filigree and overlay work?
