Good evening members of straightrazorplace my name Is Mike Dufresne and I live in Kingston, Ontario, Canada. I worked most of my life for the federal Government of Canada in the field of correctional services and retired in 2010. I am a amateur antique collector and I buy and collect almost anything that interests me that I believe to be antique and appears to be in very good to excellent condition. Earlier this evening I loaded a vintage " Schulze Weyer Razor " asking for help dating this and I have received some valued advice regarding the date plus cleaning and caring for this lovely old piece. This is a nice informative site and I will try and add photos of old razors of interest as I find them. Thank you to everyone that has posted all the information I have been reading. It has been very helpful and has really sparked my interest in straight razor collecting. I may be hooked??? Best regards. Mike Dufresne.
