Ideal Humidity and Temprature for Collection?

[derek]

I was hoping some of the museum-affiliated members could comment on ideal temprature and humidity for weapons on display. My house stays kind of dry, around 40% humidity, and I was wondering if there were any issues I should be aware of. I know that dryness is hard on ivory and eventually leather. What are the pros and cons, general rules, etc?

thanks in advance.
