Any remarks, corrections, or additions to the site are welcome at the email address pictured below.
If you want your website featured on the links page (as long as it is remotely related to mechanical calculators), email me.
If you have calculators for sale that may interest me, by all means shoot me an email - better a question asked than an opportunity lost!
If you need information about great-uncle Phil's calculator that you inherited, feel free to contact me as well, I may be able to provide you with some more information on age and value.
There is no clickable link to my email address to avoid spam, so you'll have to type it into your email program yourself - sorry about that!
