Consider roughly a reduction of 50% The chip cannot be repaired without it being visible. Believe me when a collector is looking to buy this pen they will use a 10p loupe with an led light. The crack will show they will also run their fingernail in the id of the pen barrel (id means inner diameter) the repair will be felt. Your fingernail is very sensitive believe it or not. Of course the pen had a Lucky Curve feed. Standard offering and Parkers early claim to fame. Perhaps you just wanted to see if the feed was broken? Please do heed the sage advice of those before my post that suggest you send it to a pro or just leave it alone and if you trade it perhaps the next owner can make the discoveries. I do too sincerely doubt that any "early Parker collector" will trade a one of a kind for your pen without signifcant funds going thier way. I have had 6 Waterman #20, 5 JG Riders, can't remember how many Lebouefs, several Patricians a Parker Giant but I have never owned a Parker Baby. You were fourtunate to possess one in nice condition. You seem to have no problem posting here. Look before you leap and ye shall learn.

Thank you Jerry,
I cant stress to you enough how confusing taking the section was, i mean those threads just went on and on. The pen was perfect, until this (i hope you guys do understand how small this chip is, not crack) small chip. I think i measured and it was 1/16 of an inch. This was another ebay find by me Also i congratulate you on the Waterman's you have owned, that's definitely not common to have 6 #20's at one time.
