For sale here is a Thomas and Thomas "au Natural" Limited Edition bamboo rod in like new condition. There were only 30 of these made in 1990. This one is serial #5 as etched into the base of the n/s butt cap and on the brass tube cap.

From the 1990 T&T catalog:
The T&T Limited Edition rod for this year features the natural color and beauty of bamboo combined with dramatic laminating craftsmanship. Kith and kin to T&T's 1987 "Jus' Swell," this 3-piece design is executed in unflamed blond bamboo. Again taking our acclaimed swelled butt construction to its limit, the natural bamboo grip becomes part of the tapered rod shaft, unsheathed by cork or superfluous embellishment.

Length: 7 1/2'
Configuration: 3-piece with extra tip
Line: #4 double taper or weight forward
Design: Continuous taper, extended swell bamboo grip
Finish: High gloss varnish over natural bamboo

Wrappings: Pale bronze silk

I will also include a scanned copy of the Thomas & Thomas catalog from 1990 when the rod was offered for $3,100. The rod also comes with its original bag and labeled tube.
