I use the "Silex superba", I think they stopped making it in the early 70's...your reel I think they stopped producing in the mid 90's, but I could be wrong. Depending on the condition of the reel, ie: does it spin true? General condition, etc...you should be able to sell it for much more than 100$. The milner centerpins are kinda like the newer versions of this reel. Same 4" spool size and similar setup, I think they go for somewhere between 300-500$, you could probably sell it for somewhere close to that depending on the buyer and the condition of the reel...I would check on ebay and other similar sites and see what other silex's are going for...they're great reels, very sturdy, lots of line capacity, and a pleasure to fish with...and, they only get better with age...Do you have a pic?
