Description
Finished in what was to become the standard color for the new F-5 developed by Lloyd Loar, this late 1922 F-4 may not be unique, but it's one for the collectors. It's the third one I've seen, and it's obviously all original, and in a perfect state of preservation. The ones I've seen have nearly sequential serial numbers, ending in 3,4,6, and are almost 300 instruments earlier than the earliest known signed Loar F-5. So, was Lloyd interested in seeing how the new color would impress the management?
This one has the earliest iteration of the adjustable bridge, but no truss rod. Soon after this series, the classic red sunburst F-4 would gain the truss rod and slimmer neck, and lose its top-of-the-line status
