(SOLD) This is a late 1940s Eversharp Symphony Fountain Pen and Pencil set in Burgundy, with gold-filled trim, and a flexible 14k Medium nib. The set appears to be new-old-stock, with all original parts, and a sticker still in place. I made sure the set worked properly, adjusted the nib and ink flow, but kept the original sac, as it was pristine. I cleaned the set and gave it a gentle hand polish.
Eversharp advertised this set as "A luxury set at a pre-war price." Even today, I'd consider Eversharp Symphony the most affordable true vintage flex pen. I've been getting a lot of requests for affordable vintage flex. To be honest, it's almost an oxymoron, as the demand for vintage flex is at an all-time high. Still, I was able to source this exciting set for you, and I am offering it at an affordable price.
I'd rank the nib as a medium flex, possibly even close to full-flex. It's soft and springy. It's nominal width is a Fine, though it was sold as a Medium. It has ample tipping material of perfect geometry. A smooth writer and will give you the line variation you seek.
Cosmetically, the set looks like it had not been stored in favorable conditions. There's one small nick on the top of the cap, and a couple of small blemishes here and there, but, otherwise, it's in an unused condition, at least judging by the internals. The pencil work, and I filled it with new 0.9mm lead.
