alex g 731 Posted January 15 Share Posted January 15 Just acquired this brass Mack plaque I'm assuming it's off a AC it will have a new home hanging on my wall. I'm not interested in selling it but I'm wondering if it's ok to polish it regardless. Any info on exactly what model it is off would be appreciated. Thanks 1 1 Quote Link to post Share on other sites
Frank Y 43 Posted January 15 Share Posted January 15 Why polish it? It's got beautiful patina IMO. 1 Quote Link to post Share on other sites
alex g 731 Posted January 15 Author Share Posted January 15 I agree the patina is great but shiny is nice too. I wasn't sure if it would damage it at all Quote Link to post Share on other sites

yarnall 975 Posted January 16 Share Posted January 16 Nice find. They started using this emblem in 1923 or 23 on AB’s and AC’s. 1 Quote Link to post Share on other sites
harrybarbon 220 Posted January 18 Share Posted January 18 Alex I have the same brass plaque, they are rare pieces it seems. Mine was dull and near black with grime, I have done a gentle clean and now looks similar to your plaque. I tried to polish the back side a bit harder to experiment to see how bright the brass may polish to. It did not/would not come up very bright, so I think it may be the quality of the brass made at that time. I cleaned all the grime from mine and it still has the old patina look. I have thought about giving it a clear coat but decided to leave original, been 1 year now and no change in the patina, has not dulled at all. Quote Link to post Share on other sites
