Series 2000 Flat Top Fountain Pen question

[mrmartyking]

I am going to make a couple of these to try them out but I am seeing some concern about something scratching the finish. What is the scoop here?
I was looking for a slim fountain pen but if there are kit issues, I would like to know how to avoid them. Or maybe everyone is great with these. Feedback please.
Thanks

The issue I had on the few I made was the inside of the centerband .... I always had to file it some for the pen to screw together.
I suspect that is the area that causes scratches when the pen is posted.

On a positive note, it is one of the slimmest I know of available as a fountain pen.

Any other people see these scratches?

Is it caused by the center band or the brass tube?
