I could do that, a long time ago. Slide rules and calculators changed all
that.

I have those too. My mother made crafts and sold them during the holidays.
I have some of those too. My dad came back from WW2 with a few Nazi
souviners and I have some of those too. Especially neat was the officers
holster with a .25 auto pistol in it.  I used to sneak it out of his
drawer  when I was a kid and take it out for target practice. I always
bought new ammo for those occasions and left his alone. I don't think he
ever knew. I did some gun-smithing on it for him some years later,
replacing a lost ejector after seeing the one he attempted to make for it.

Ahhhh. Do you know how to change it's name via the echolist so people
don't lose it during the transition from BAMA to NASA_UPDATES?
