I believe it is a good one also , but unfortunatly there are alot of collectors that tend to assume that just because some well known "Expert" says that they are bad then it is set in stone as BAD .
Example ...
I bought a uniform a few years ago that came from so called known experts collection .... "BOB" ........! . The sleeve eagle was machine sewn and looked original . he even posted the uniform on WAF and all collectors that posted said it was good as gold ...loved it . nothing wrong .. all original .
When I aquired the uniform , I loved it too , as it is an original uniform , but I felt there was something wrong with the sleeve eagle .
I posted scans of just the eagle on WAF without telling were I got the uniform . The response was all bad . and 3 so called experts said that the sleeve eagle was a 1970s reproduction .
So unfortunatly , in this hobby if you are popular then for the most part you will not be asked to explain why YOUR item is not good . But if you are the average collector , then you need all the referances in the world for your item to be good .
Zeller , I have 2 flat enamel pattern membership badges in my collection also , I believe that they are good but I can guarentee that some self proclaimed EXPERT will also say that they are bad .
So if they price is right and your gut says ok then be ok from years of research via collecting with your purchase .
