new rod taper. - Lazybee45

OK, I was at my fly tying class tonight and Doug, the guy who "owns" the room 
(he is a physics teacher at a local High School and he allows us to use the 
room) and I have been discussing bamboo rods.  He said he got one on th ewest 
side of the Rocky Mts in Colorado for a decent price but it has no name on 
it, Ddown locking reel and all Cork grip and reel seat.  Nice two piece of 
about 6' 3"  and he is using 5 wt line on it.  I tried it and it casts VERY 
nicely.  We were casting in the hallway at the school, crouching down and 
angling the rod so it wouldnt hit the cielling or lockers.  We were putting 
the line out 50-60 ft under these conditions.  NICE feel!  I measured it and 
this is what I got.  NO Garuntees!  But here is the taper

The balance is taken up by the butt and reel seat  Overall length is 75.75 
inches
The ferrule is between  35 and 40 inch stations.  
    How much do I deduct for finish?  I really want to make one like this 
myself!  Anyone have any idea of who might have made this rod?
