I was googling last night and came across a Christie's (South Kensington, London) auction catalog for their upcoming sale on November 23, 2010 and found this wonderful Edwardian bronze horse model wearing a side saddle!
It is described as "AN AUSTRIAN COLD-PAINTED BRONZE MODEL OF A HORSE BERGMAN FOUNDRY, VIENNA, EARLY 20TH CENTURY. With a side saddle, the underside stamped 'B' within an urn, 'GESCHUTZT/3260' 11 5/8 in. (29.5 cm) high."
I would so love to own it but with an estimate of £5000 to £8000, it's a "bit" out of my budget that I use to occasionally treat myself to a Breyer horse! LOL!
