I found this str8 at an antique shop. The price was very reasonable, I think. I purchased this to practice on my restoration of str8s. There are no markings to ID the Manufacturer. The dealer thought that maybe it was a hybrid, or put together with various parts. His decision was mostly based on the fact of the additional metal covering the tang and monkey tail. I however find a couple examples of similar setups in STANDARD GUIDE TO RAZORS 3rd edition by Ritchie & Stewart. Don't know about the box, but it came with the razor. Thank you for your time and help.
