HP 19C Spring loaded Thingy?

[rprosperi]

And note that I've read that not all 19Cs have that; though mine does, as do the others I've owned but are now gone. While not 100% certain, I'd guess that they removed it to save cost, rather than added it to prevent theft.

So, there you go... there's another version you have to locate and acquire.

Does anyone here have a 19C without the security tab?
