This is the Vosseler RC3 reel, but sold by Mike Barrio fly lines, it has Barrio on the side instead of Vosseler, there is no other difference.
The reel is rated as a 7/8wt and 83mm diameter, but will take a 5 or 6 wt and looks perfectly okay, i have used 6wt lines on it.
It is in virtually unmarked condition and i can only see one tiny pin prick mark on it, both spools are unmarked, i bought the spare spool from Vosseler last year and has not been used.
It is a very high quality reel with a simple drag system which consists of 3 spring loaded bearings which can be taken out to vary the amount of drag is on the spool, two spare bearings are included.
The reel and spool come in pouches, the reel pouch is brand new and i purchased at the same time as the spool.
