Hello and welcome to the showcase of my collection of mechanical calculators!

As I’m in my twenties I’m far too young to have used any of the calculators on this site other than for fun. My only experience with these calculators is what I have found out myself or what I have managed to find online on other sites. Therefore, I recommend that you to take the information found here with a pinch of salt and not to rely on it in any important way!

Since I have limited time to spend on this page there are currently calculators that I own but haven’t had the time to add to the site. So, if you have any request or questions regarding calculators not on this site, feel free to contact me through the contact page.
