I have a small permanent display of my pens in a cabinet in the shop at the Dales Countryside Museum in Hawes. Recently, a customer asked to look at an inlay violin Sierra pen in the display. The shop assistant opened the cabinet and gave the customer the pen to examine and then served another customer. By the time the assistant had finished serving the other customer, the one looking at the pen had left the museum, leaving the pen in pieces on the counter! I have no idea how he did it, but he seems to have unscrewed the two parts of the mechanism and rammed the lower part hard down into the cap end of the pen body, where it has stuck fast. It is too deep for the other part of the mechanism to engage the thread and all my efforts to remove it without damaging it have proved fruitless. Any suggestions would be most welcome.
