If I were building a period correct 289FIA, I'd use the 48IDA.

Actually your information is not completely accurate 48IDM Webers (sand cast) were used well into 1964 by SAI on, 289 FIA Cobras, Daytona Coupes and King Cobras when they were eventually switched out to the 48IDA Webers (die cast). The first three of the five 289 FIA Cobras built had 48IDM Webers from new (2259, 2260 and 2301), CSX2323 being the first 289 FIA Cobra built with 48IDA Webers and CSX2345 being the next and final 289 FIA Cobra. Per your Registry reference, it wouldn’t be the first time the Registry had incorrect information.
