In 40 years in and out of the sport and twenty years of buying and selling
old rally equipment, I never heard of Lafayette rally equipment. I tend to
agree with others that these are electric counters that someone cobbled up to a
Stevens or homemade sending unit. I have encountered stuff like that over the
years. One such encounter might be of interest.
When my Turner vintage race car was under construction, I bought some parts
from a former Sprite racer in Boiling Springs, Pa. named Ray Stone. As I was
poking around his garage, I noticed several identical spiral bound orange
booklets on a shelf. Yup, it turned out to be copies of "Floyd's Factors", the
well known book of minute per mile factors. Ray was Floyd's son. I managed to
pry a copy of the book from Ray. Also on offer that day was a pair of
electrical counters, a backlash of wire and some undocumented gizmos. Clearly,
it
was the remains of an odometer set up built by Floyd. I don't remember the
name on the counters, except that it wasn't Stevens.
Small world.

and quite possibly using a Stevens inline sending unit with cam driven micro

In all my research I've never seen "Lafayette" listed in any rally book as a
supplier of rally equipment. After looking at the photos I think Walt is
correct, it's probably a home brew using Lafayette counters, similar to what
many did with Veeter-Root counters.
