Kow's 1934 Panhard has a three-piece panoramic windshield.
The 1933 car from the Lane Museum only has a flat windshield.

What about the dog? I think it's a Sheltie.

According to “Priscilla in Paris” in a July 1934 edition of the posh Tatler magazine, this event was an oh, oh, so exasperating affair for the elegant ladies taking part but the blue Panhard, Mme. Kow and the young girl driver did get a mention:

“The Concours d'élégance feminine en automobile took place this year at the Jardin d' Acclimation of the Bois de Boulogne, and some three hundred beautiful cars, driven by exquisitely dressed women, snailed past a jury composed of famous artists, such as van Dongen, the arbiter elegantiarum of Paris; M. André de Fouquière, and other celebrities of le Tout Paris. One of the prettiest outfits was that of Mme. Vera Goullet, who was driving a dark-blue Renault, and Mlle. Blanche Montel, all in white, at the wheel of an all- white Delage, ran her a close second. An amusing couple were Mme. Kow in a blue Panhard, followed by tiny, seven-year-old Jacqueline Kami, in a miniature toy car that was the exact replica of the big one. One of the special mentions went to the great screen and stage star, Mlle. Gaby Morlay, who was in such a state of exasperation that, she vowed, she would have liked to drive right through the jurymen's bench. The competitors had been herded into line for the drive past at ten o'clock; at two p.m. they were still edging forwards, an inch at a time, and Gaby ought to have been on the lot at the Joinville studios before mid-day. Once in the line, hedged in by the spectators, it was impossible to get away, and a good deal of the language I heard was not at all en rapport with the dainty appearance of the competitors.”

It had been observed in 1931 that Panhards were generally dark blue and a report of the 1934 Paris motor show noted that the only new idea was Panhard’s clever design for the A-pillar: “… removal of the single upright altogether, and replacing it by two slender uprights separated by a four-inch glass panel... a safety-first feature of great value.”

"BELKA" is simply the internal code for the specific type of car, its engine and body style. The underlying five-letter code was introduced in 1927 and enabled a precise identification of any works version. See: Bernard Vermeylen, Panhard & Levassor entre tradition e modernité, p.118
