I've added a donation button to Milivault for anyone who'd like to help keep the site alive. Server costs, building case studies, cleaning and fixing data, and adding new tools all take a lot of time and money. Any support through PayPal goes straight into keeping the site running and improving it over time. You can find it on this page:
https://milivault.com/about/
I also launched a new WW2 German helmet lot number lookup page here:
https://milivault.com/helmets/
You can use it to look up lot numbers, maker codes, shell sizes, and branches more easily. This page combines the German Helmet Vault lot number list with helmets I've manually entered from my own records. All credit for the original research goes to German Helmet Vault—this is just a more searchable way to explore it.
Finally, there's a new case study live:
Waffen-SS Single Decal Helmet – Case Study and Price Assessment
