rossi wood grips?

Hi, I met a gentleman at a gun show who was selling a rossi m461 with wood grips, when i asked he said they were for a colt d special and "they bolted right on", when i looked closer they looked like they had light sanding done on the rear corner but thats it. I have owned this rossi model before (first handgun) but eventually sold it. My question is if anyone else has ever tried this maybe with a different firearms grips (s&w,taurus) before. I curently own a m351 rossi and would like to own more rossi's but the grip problem is detering me from doing so. If this has been discused before I apologize I searched and didnt find anything. thx
