This B&C J-45 takes its inspiration from the small number of Banner-era guitars that left Gibson’s Kalamazoo factory around 1945 with maple back and sides. Wartime material shortages produced considerable variation among Banner J-45s, including examples with laminated maple bodies, multi-piece maple or poplar necks and non-adjustable wooden neck reinforcement. B&C deliberately use solid, moon-logged maple for the back and sides rather than reproducing the laminated construction of the surviving reference guitars. The top and braces are air-dried European red spruce, while the three-piece poplar-and-mahogany neck is reinforced with a maple V rod. A thin pure-cellulose finish and genuine celluloid firestripe pickguard preserve the unmistakable visual character of a wartime slope-shoulder. Because the solid-maple body and modified neck reinforcement intentionally depart from the original, this model is best described as a historically informed Banner J-45 recreation, rather than an exact replica. It retains the materials, construction language and wartime individuality of the originals while adapting the design for this particular instrument.
