There were more than 100 German Sperrbrechers active in WW II. The German producer Förde specialized in creating many of these as 1250 models.
I have taken photos of my Sperrbrecher models. I have added a description and a price to these photos and then put them all into an iCloud album.

If you are interested in purchasing any of these models, please send me an email haralds@thescheels.com.
