This Croxley arrived the other day. When I saw it advertised I realised that it had the wrong clip. No problem, I thought. I have a couple of Croxley clips. However, neither of my clips would fit. The internal diameter of the washer is 10.6 mm, considerably larger than either of my clips. I had to revert to the clip the pen came with.
How can it be that Croxleys vary so much? One would think that such things as clip screws and caps would be identical, or nearly so, in a production facility of the late 40s. It’s almost as if they were hand-made.
On the same subject, a friend is looking for a plain clip for a National Security with an internal diameter of 11.3 mm. That’s BIG!
