Needing Mettco Details

[williamlharper]

Planning a Mettco 125 ISDT replica build.  Finding examples with standard 125 ISDT colors (seems these were the 1973 and earlier bikes) and some red tanked, white framed versions (125s/100s?). Found one green tanked, white framed version.  Does anyone have first hand knowledge of the difference between the earlier green tanked 125s and the red tanked versions?  Would really like to know what the actual Mettco bike's configurations were, although there are some good looking tribute bikes out there.  Thanks for your time...
