Here I found some more display/advertising models made by the modelmaking company Alchemy. These are not my favourite examples of their work but they demonstrate the best example of what Im trying to achieve with my own pen model.
I had always assumed that the pen model would be used as part of a window display, however as seen here it might be more likely to be used as part of a sign over a shop/building.

What suprised me about these models was the simple ways that they were made. Mostly using metal framework and resin and polystyrene. Similar to my attempt to make my pen by casting into pipes they have made their models with minimal machinery and used materials that can be manipulated more easily by hand.
