Remember from the history of Montegrappa that in 1946 a fire in the celluloid room burned down all of the records department as well as damaging some of the manufacturing areas and so Montegrappa abandoned celluloid as too dangerous.
By the 80s though understanding of celluloid as well as advancements in monitoring, data acquisition, machining and computer controls had progressed to the point that Montegrappa decided to return to celluloid.
There is nothing quite like celluloid for the body of a pen; its warmth, depth, colors, sheen cannot be duplicated by any other modern plastic resin today.
With the Symphony line Montegrappa again reached back to its roots to create two lines that used celluloid or natural briar for the body and cap. The Brier & Sterling series used Erica Tree root. The Erica Tree root is actually a nodule, about a foot long and maybe nine inches in diameter from a species of heather common to the Mediterranean. It's harvested when it is 30-60 years old and then dried for a period of months, often years. It produces a beautiful very hard heat-risistant wood often used for making pipes.
The Symphony line (and the Brier & Sterling) like the Reminiscense and Espressione have a threaded end so that the cap may be screwed in place when posted. They are slightly slimmer pens than those others but about the same length.
The Sterling cap band is wide and engraved with the Montgrappa crest.
The 18k masked nib sports the Greek Key motif.
The Symphony is a medium-large pen, about the girth of a Montblanc 146 but slightly longer.
The Brier & Sterling pens are the same size as the Symphony and the wood feels great in hand and has the depth found in old furniture and fine pipe bowls.
There were a few a companion lines. One was called Harmony that was the same size and shape as the Symphony but with a resin body. There is also the much shorter Micra (cartridge only).
The successor to the Symphony line is the Emblema. Like the Symphony it is a celluloid and Sterling silver pen with the Montegrappa Greek Key 18k nib.
While the Symphony has a wide cap band with the engraved Montegrappa logo, the Emblema has a narrow cap band with an extension of the section visually separating cap and body.
