The Mackenstein Field Camera (tailboard) is a French-made wooden tailboard field camera, a folding plate format design of the type used for large-format photography from the late nineteenth century onward. Mackenstein was a Paris-based maker, and tailboard models of this kind were positioned as portable field instruments for studio and outdoor plate work.

Auction data for this model is extremely thin: a single UK saleroom hammer result from 1998 records a price of £115, which gives only a historical reference point rather than a current market value. Because that figure is a wholesale auction-hammer result from nearly three decades ago, it should not be read as what a Mackenstein tailboard is worth today, and any present-day estimate of value or likely sells-for price would require fresh comparable sales.
