Cave letters back & forth between customer. / price lists and envelope
"We do not make cheap mirrors or diagonals, but we are spending a lot of time correcting them and reconfiguring them for the purchaser who has been led to believe he could get something good for an absurd low price. Quality always commands fair prices. This is true with mirrors. Our optics are the result of highly skilled workmanship.
They are thoroughly tested before leaving our plant, are star tested, and are guaranteed to give satisfactory performance."
"All telescope mirrors produced and sold by Cave Optical Co., are entirely manufactured by our opticians. They are all made of Pyrex brand glass, and are first ground flat on the back side for ease of mounting. Each mirror is then ground to the focal length as ordered by the customer. "
Alika Herring, Cave's extraordinary mirror maker, testing a mirror.
