"Could it have been placed there in part to help damp some road vibration?"

That's not a bad suggestion. What I had always heard was that certain European bike manufacturers routinely installed the wooden plugs in case the braze between the steering tube and fork crown failed. I'm not sure how much that would help???

I know of several shops that inserted a piece of wood doweling or old broom handle into the bottom of the steering tubes on all of the frames they built up and pro bikes they assembled.

I recall 3-4 bikes that came into our shop with complaints that "the fork was loose". Sure enough it was. The brazing had failed and the front brake mounting bolt was all that was holding the forks on!

These were all better name European bike boom era bikes (names withheld to protect the guilty).

I never heard anything at all about the wood being a reinforcement for the steer tube or the head tube, and do not think it would make that much difference in the strength at all.
