Make me an offer, cleaning up my workbench!
Used 3-bolt chainring guard, 116mm BCD (100.4mm between the centers of adjacent mounting holes, see Sheldon Brown’s site to check your BCD if unsure). Removed from my ‘72 Raleigh Grand Prix (not sure if it was original to that bike or not). Some pitting in chrome (see photos for condition), otherwise straight and in good shape. Have no need for it and seems a shame to scrap it, priced to sell!
