I'm searching for a small model based on Wilder Penfield's map of the
somatosensory cortex in the human brain. I've found images of such a
model at London's Natural History Museum website:

What I'm interested in is finding somewhere that I can purchase a
little model of one of these guys. It doesn't have to be the exact
same as in that picture, but something very similar. I've been looking
for months, but I'm sure you all have much better resources than I do.
If you can find what I'm looking for, the tip will be very generous.

I have been looking for years for one myself. I have a
roughly-executed model by one of my students, but I keep meaning to go
to the sculpture studio and commission one. Good luck!
