They certainly look overall like a model 33 and presumably are similar inside.
An easy way to tell the two apart is that the model 33 has a four-row keyboard,
with numbers on the top row just like today's standard keyboards. A model 32
has a three-row keyboard, with the numbers shown as shifted values on the top
row letters (QWERTY...). That three row keyboard is a common feature of Baudot
terminals, though a few manufacturers use a four row keyboard and either lock
out some of the keys depending on the shift state, or do a letters/figures
shift automatically, I'm not sure which.
