I haven't come accross one of those...
Syslight said something about the Kronpunkt on the forum (http://straightrazorpalace.com/razor...kt-38-a.html): Dovo purchaced the brand name Kronpunkt from Paul Heups in 1969. I do not know if Dovo made these razors before that time under contract. i have a #91 that is a an excetional shave and it is stamped "Paul Heups Solingen Germany" on the back of the tang.
Other references here: DOVO Stahlwaren Bracht GmbH & Co. KG and DOVO Solingen / Enterprise (North Rhine-Westphalia) - Economy-point.org

There is also a brand named Kron, from Germany, alife between 1919-1922 (cf. Standard guide to Razors by R. Ritchie & R. Stewart, p. 156); but I don't knwo if they are related...

Hope this helps.
