I just received this pen yesterday from an eBay purchase. I wish I had taken a "before" picture, but I neglected to do that. The pen was quite dark. The lever box was broken and the clip was loose. The sac was sort of melted onto the inside of the barrel. It was just about the most difficult I have ever had to remove. After I removed it, I noticed that the color had lightened up considerably.
Similarly, a lot of the dark color of the cap seemed to be the result of ink residue. I ended up pulling the inner cap to tighten the clip, and was also able to clean the cap completely. It also became lighter in color. With the unstable Persian plastic, much of the pen becomes transparent, so whatever is inside shows through. Thus, you can see that when I replaced the inner cap, it results in a darker area at the top of the cap. I found myself wishing for some kind of wild colored inner cap, instead of the black one. I replaced the whole lever box assembly, and reset the nib.
Final results look pretty nice, I think. The pen is not really the same as the original Persian, but is still quite attractive. I found myself thinking that if you could paint the inside of the cap and barrel with bright patches of blue, pink, and green, you might be able to come close to the original color. Hmmmmm ......
Thanks for sharing!
