I may be wrong but that picture sure looks like the D frame for colt as in the second version detective special,diamondback,agent, grips.Go over to a local gun shop that will work with you.I have extra grips that are rubber and wood for that model gun.PM me and I will be happy to send them to you and if they don't fit just pay the kindness foward and give them to someone who will use them......God Bless.....Mike
