Hi. I know this has been discussed (at least I think I've seen it discussed) but searching for "+ + Red Tip" only seems to provide me with a lot of links to Red Tip discussions but nothing on the + + (short of going through 20 pages of referenced threads).
Can anyone remind me as to the significance of the + + on the underside of a Red Tip? (and I guess a similar question to the O O -- not date code -- on the underside of a Blue Tip).
It may not be "significant", but given that I cannot remember, any refresher would be appreciated.
Thanks
