Eclipse is a NYC based maker that goes back to the 1910's. Often dismissed by pen snobs as third tier, they made well built, attractive pens, but fitted them with undersized, mostly Warranted 14k nibs -- hence the sneers. (A few nibs carry the Eclipse imprint, but that's not the rule) Not at all innovative in function or materials, mostly lever fill with shapes and colors that followed the bigger pace setters.
Sometime in the Forties they opened a plant in Toronto and soon after closed the domestic facility. Canada continued making increasingly cheesy pens into the Fifties, until it finally gave in to the ball point. The eclipse of Eclipse. All of the Canadian pens I've seen have gold plated nibs, which makes the OP's pen very interesting.
gygtaylor's Black & Pearl cigar, a 1940's shape, uses the same celluloid as this American made c. 1925 Flat Top, but reflects the declining workmanship of the brand's later years. Note the glued on end-caps separated by a knurled band.
Fascinating pen.
P.S.
This background is very superficial. A search will bring up lots of interesting detail.
