So finally i found a white SJ to complete my collection
but the clip and the barrel jewel on it is broken, sorry for the potato pic but i was excited and forgot to take a picture and just disassembled it and its now soaking in soapy water.
So the pen looks white in the image but it has turned yellow and has red ink stains all over it and the cap and the inside of the barrel have turned black due to ink deposit, also the j bar was completely broken.
Now i will try to look for a donor pen, don't want to ruin a perfect pen. What would you guys suggest while extracting, the barrel jewel and the clip of the pen, as i have read these are the most hardest jobs to do, so i will have to be extra careful if there are any guides or any suggestions please let me know
