The Rochester Camera Mfg. Co. Pony Premo No.3 is an early American plate-format folding camera from the late 19th century, produced by one of the Rochester, New York makers that fed into the eventual consolidation of the US camera industry. It was positioned as a portable plate camera for amateur and travelling photographers of its period.

Evidence of what a Pony Premo No.3 is worth in today's UK market is thin: the only recorded saleroom result we have is a single 2024 hammer of £35 at UK auction, so the price sits at the low end of the antique-plate-camera spectrum. With just one wholesale auction data point, that figure should be read as indicative rather than a reliable median, and condition, completeness of the original plate holders, and bellows integrity will swing what a clean example sells for.
