i'm far from an expert on that era of 1911s but i'd say no. they look like newer replacement grips. i believe original grips would be a more darker brown look and less shiney than those redish brown color grips.
Thanks y'all for confirming my suspicions. I had too many questions just based on appearance. I have been just looking at pictures trying to compare images in my hopes to refresh my knowledge base, since I have been playing with SAA for the last 35 years...LOL
