A Very Interesting Straight Razor

This is a very interesting straight that belongs to s friend but he wants me to sell three straits for him because he wants to save & buy him a 1911 45 auto. This is one of them. It is a Mar-ing Razor Co straight razor that has 3 interchangeable blades & I don't see one on the bay & haven't seen one but I'm sure they're out there. I find it very interesting & he has taken very good care of it, it is oiled so that it won't rust. I still like my Jaques Lecoultre multi-blade straights, especially my 7 day set. I have a 5 day set which was his but he needed some money one day & pawned it off to me but I gave him first choice if he ever wants it back & he has told me that he would like to get it back one day. I also have two Lecoultre 2 blade sets.
