Scale Aircraft Conversions (SAC) is a Texas based company that has been marketing resin and white metal parts for scale model aircraft for over 20 years. They endeavor to be accurate in their moldings, claiming to correct inaccuracies if found. I have bought about a half dozen of their metal landing gear sets in the past, all of which have turned out to be excellent replacements for the plastic kit parts.
SAC’s two-piece landing gear set #72180 is labeled for the ‘60s vintage 1/72-scale Hasegawa F-104G/J, CF-104 kit but I find that the set matches the more recent 1990-issued F-104G/S landing gear as well. A comparison photo of the metal SAC main gear with the F-104G/S gear is shown herewith.
