While working on a project today I pulled my supply of 92693c01s and noticed
that some looked different. Further investigation revealed a different part number
on the side (37773), numbers on the dark gray part (2 variations-(31x9) & (46x9),
and differences in the construction of the main housing. All three parts have
the Lego logo, connect and function the same. Is this known variant are new piece
for the catalog? In the photo 92693c01 is at the top the lower two are 37773.
