Here’s one of my favorite Frankenpens of all time.
The Ambassador body, which I’ve not been able to find any info on, came in a box of parts pens. I thought it looked neat. The steel nib wasn’t salvageable, but the rest was in great condition, and a spare Waterman #2 left oblique nib fit perfectly. I did have to substantially deepen and expand the feed’s channels, but after the ebonite dust cleared I had myself a wonderful little pen that I dubbed the Ambassador 52. I consider it to be like a “sleeper” car; it looks cheap until you get in on that long Rhodia highway to stretch its legs tines.
The ink is Sailor Sei-Boku, one of my favorite blues.
This is an older review, and my opinion of this ink now is mostly negative, though I will admit that I haven’t traded the bottle and do still use it, but only with fine nibs. It’s an interesting concept and message, but the end result and usability of the ink is very limited.
Oddly enough it’s better behaved on copy paper:
Here’s a drip test:
And a full soak test:
I can’t tell you exactly how long it soaked, but it was probably 10-30 minutes. Washing away the yellow component of the ink really doesn’t take long to do.
