I think David Wells sent me this picture and provided the ink pencil sections to show the similarities. In my collection I have a 115 with a nib and I believe this has simply been converted by changing the section. However, the biro version is more daring.
This pen has no imprint. The cap has a standard oblong based fixed clip, while the barrel has a lever identical to the levers on early Esterbrook relief pens made by Conway Stewart. I think it was a pen made in the factory from spare parts.
When I bought this pen I thought that I had just discovered a new number. It had the right clip, right lever and right nib, so although the imprint was faded and scratched except for the number - I took it at face value, particularly because I thought that the candle flame pattern of plastic was perculiar to Conway Stewart, and I bought it from a reputable dealer. Then I found this Summit pen at an antique fair and all was revealed.
The barrel is clearly a beautiful 417 cracked ice (rare), but the cap is much later and is from the 27, 28, 58 60 series. However, it has no bands and my guess is that it has been shortened.
