It is not a real springy nib like a Pelikan 1000.
It is a 'springy' nib...a flex set between 'true' springy regular flex and semi-flex; both spread their tines 3 X a light down stroke....a 'springy' nib bends well at the tip, but only spreads it's tines 2 X a light down stroke.
A 1000 can be as some folks say a nice springy nib. The one I tried in a B&M was semi-flex. I have some 27 semi-flex nibbed pens.
Another reason not to buy is both are 18 K nibs, so if you bend it a tad too much....it remains bent, where a 14 K nib would not have that problem.
Modern MB nibs seem to run wide....defiantly do to a vintage '50's nib.
I would suggest getting a 149 from the grand '50-65 nib, that would be either semi-flex or 'flexi'/maxi-semi-flex or the '66-75 that has a tad less spring to the nib in comparison.
The older vintage nibs are not on the whole quite as blingy as modern, but I like them. My 742 is bi-colored, so rather blingy for the time.
Of course mine are not a 149.
I have two standard sized pens a rolled gold 742, ('51-55) with that 'flexi'/maxi-semi-flex and a 234 1/2 Deluxe semi-flex KOB, ('52-55)
Back then the 146 was a medium-large pen, that grew into a Large pen in the '80s.
It all depends on what you want the nib to do...I'd suggest a '50-75 one with a better nib, than the only 'springy' '76 to modern.
Agree with stogy...it is after all a '30's Sheaffer New Balance clone.
