Read somewhere that the diamond cutout was a sign of Tange lugs.
Okay, thanks. I noticed your Univega has a triple butted sticker, so I assume it's a Miyata-built frame. My 1981 1000 has the M cutout, but not the diamond. For all I know my girlfriend's 1986 1000 probably has the diamond, but I've never noticed it. I'll check tonight.
