UBB.threads Forums Edged Weapons Rohm Dagger Forum Is this SA Rohm Authentic?

Hi,
I am very green when it comes to WWII collecting. I just purchased an SA dagger with Rohm’s signature on the back. I know I probably should have waited until I educated myself about the forgeries out there, but I felt this looked too good to pass up. I hope I made the right decision!
Can some one tell me if this is an authentic SA Rohm dagger?

PS. How do I add more then one picture?

Thanks,
Michael
