I found that my oldest HP-41 case leaves a powdery residue on the calculator. Are there any suitable replacements for it? Preferably one that fits an HP-41 without a card reader.

Yes, that's how to solve this problem.

Good point, my suggestion above only applies for a 41 w/o card reader.
As for Spice cases, I never tried that before now; nice idea
I found the 41 fits perfectly in the larger/padded style Spice/Spike cases, but not really in the smaller/un-padded style. The latter style is too tight, and also, un-padded, which IMHO is too dangerous for carrying a 41; one drop in that and it will likely cost you post damage.

You can find them on their website or on TAS. I have several for the 41's I acquired without cases. They have a decent amount of padding and include a belt loop if you really want to go retro. No engineering student in the 70's was without one!

The comments about other cases made me look in my drawer for my unrestored HP-67 which has a nice well padded case, though it is a bit thick to accompany magnetic cards and quick reference cards. It seems like a good fit for the HP-41, I will borrow that for a while from the HP-67.

Hi, nice case, but maybe just one piece was available

My 41CLs are in the HP-70 case. The zipper goes nearly down to the bottom of the case and you can easily get out the calculator out without scratches.
