I'm trying to get this unknown pen from a pen lot purchase back in working order. Unfortunately, the clip is broken off. Also, the clip slot is perpendicular to the barrel and it seems that a s shaped clip would work as a replacement. When I took out the inner cap a small tab fell out which I assume is what held the clip in place. However, I don't know what these types of clips are called and therefore can't search for them. If anyone can help, or knows of a source for these types of clips, it would be appreciated.
Is there a parts exchange somewhere, that I could post a request? Or Do I have to wait for the next pen show to scrounge in the junk pen piles? I guess I would want a no name clip so not to confuse the issue, if I ever get it repaired.
It has "Arrow" written on the lever and a Signature 4 Made In USA Nib (See pics). With the clip missing I have no other information, so I can't be certain about the make of the pen. When I search for arrow pens all I get is Parker variants.
