The Toa Gelto-D III is a Japanese-made compact roll-film camera produced by Toakoki Seisakusho. It belongs to the mid-twentieth-century class of small Japanese viewfinder cameras using 127 roll film.

Sales data for the Gelto-D III is extremely thin: a single UK auction-hammer result on record sold for £57 in 1999, so any current 2026 worth or price guidance has to be treated as indicative rather than a reliable median. Because that sale is decades old and prices for niche pre-war Japanese roll-film cameras shift with collector interest, the figure is best read as a historical reference point rather than what a clean example sells for today at saleroom level.
