Here is a mysterious Frankenpen. I bought it as a Wyvern but, searching through Google images, I could not find another that looked even remotely like it. It was referred to a Wyvern collector. He confirmed that it was not what it appeared to be and suggested that the clip, which bears a Wyvern image, had been filched from some other pen. Taking it from there, I found that the donor for the clip was probably a Wyvern Consul of about 1949. The cap soon revealed itself to be from a Mentmore 46.
The rest of the pen has so far defeated me. I would be grateful for any suggestions. The nib is unhelpful, being a “warranted 14 carat.” I feel sure that I have seen that short, flush section before but I cannot for the life of me place it. Most annoying. There is no writing on the barrel.
It is of course, a complete Frankenpen, but well put together from disparate parts. Somebody has done a good job and created an attractive pen.
ETA: It has been suggested that the section looks like a late Blackbird. I see the resemblance.
