Dallmeyer (J.H.) Brass Lantern Projection Lens

{"overview":"The J.H. Dallmeyer Brass Lantern Projection Lens is an early projection optic housed in a brass barrel, made by the long-established London optical firm founded in the Victorian era. Because that figure is a wholesale auction result rather than a retail asking price, dealer-listed examples in 2026 are likely to sell for more, and condition of the brasswork and glass remains the main driver of what any individual example is worth today.","buying_guide":"Inspect the front and rear elements for fungus, haze, internal cleaning marks and any sign of separation between cemented groups, as these antique projection lenses often sat unused for decades.
