[QUOTE]\nGoogle is your friend: "Nikon lens part diagram" - images\n\n[URL]https://www.google.co.nz/search?q=nikon+lens+parts+diagram&hl=en&newwindow=1&safe=off&prmd=imvnsfd&tbm=isch&tbo=u&source=univ&sa=X&ei=Itz_T8fgCoafiQfZq9iBCA&sqi=2&ved=0CGkQsAQ&biw=1428&bih=976[/URL]\n\nRegards,\n\nEric Stevens[/QUOTE]\n\nAs far as I can tell, none of the diagrams on that page will be\nhelpful in replacing the part that Arklin is replacing. The schematic\nhe wants (and I want) shows how the bayonet mount ring piece is\nattached/removed/added to the lens. Strangely, for a search on Nikon\nlens parts, many of the diagrams are for Olympus lenses. There may be\na reason for that that I don't know. It's not my bag.\n\nWhile we are on the subject of newsgroup postings, how about you -\nEric - adding a sig line delimiter so your "Regards, Eric Stevens" is\nstripped when replying. What is it? Two dashes followed by a white\nspace character on a single line?
