Some time back, Mike Kirk made me aware of the fat-barreled MP-10 pencil after he spotted one on either ebay or etsy.
These have a different barrel shape than the typical nose-drive pencils one usually finds in early Pardners sets or singly. They're cheaply made, but come in a variety of colors. The MP-10 has a straight sided barrel for most of its length rather than the usual tapered barrel. The above MP-10 mentions a J-10 Jotter, but what is a J-10 Jotter? I just had one of those "oh s**t!" moments when, while looking for something else, I opened these two sets I've had for several years. Note the regular Jotter at the top for comparison.
Thanks, Mike!
