it's parker 43C nice razors. According to some reviewers the only flawed part is the head which is glued and tends to detachI got the metal Parker found here
Heavyweight All-Metal Triple Blade Razor from Parker Safety Razor - Accepts Mach 3 and Gillette3 Blades https://www.amazon.com/dp/B008Y2ZBTG/ref=cm_sw_r_cp_api_i_MQ.GDbQ5V5TFG
It’s nice , heavy and would satisfy most DE users if they used carts. My only issue is the head that clips to the Mach 3 spins off in the way a three piece DE razor would. It can be glued on ,but it’s by no means a deal breaker. I’m happy with it .
