That looks like a Slim Twin. I have one and they are great shavers. You can't buy replacement carts for them anymore but Atra carts will fit your schick handle. Every now and then NOS Slim Twin carts will show up on Ebay. Clayton Sent from my LG-K450 using Tapatalk
Thanks for the information. I thought it might be able to use Atra cartridges, but I wanted someone to confirm it.
