Brian,
Between January 1984 and June 1990, during the period in which I made Masis, on the underside of the bottom bracket was stamped "M" followed by the frame size, as in "M56." Opposite the "M56," would be a four-digit number that signifies the frame's build-order within the given year. "7045" was the 45th frame built in 1987.
Thus,
1984 M56 4xxx 1985 M56 5xxx 1986 M56 6xxx 1987 M56 7xxx 1988 M56 8xxx 1989 M56 9xxx
1990 M56 0xxx, or something other than a "0" to signify 1990, as I don't remember and I haven't found my records for this year yet.
Whatever numbering system ocurred after June 1990 would have been devised by Ted Kirkbride, and stamped into a quantity of 3Vs for a short period, probably up until the year that Jim Allen moved his shop across town, at which time I don't think Ted Kirkbride then had a frameshop to build in. After I left, lugged-steel GC production went to an Italian builder, Mondonico or Billato, still distributed by Torelli, still painted by Jim Allen, with yet another numbering system.
