Not in any reference I have seen
The Mark IV was not made in .32 caliber. It was in caliber .38-200 (the 38 S&W). Value is $200 and up, depending on condition. A SIMILAR revolver is made by IOF in India in caliber .32 S&W Long, and sells new (in India) for about $1,300 USD (no competing companies).
POSSIBLY a Spanish revolver (Largo indicates the .32 Long cartridge). These were made by the thousands by multiple, small gunmakers in Spain.
Usually a revolver, although a few rifles were made in that caliber.
No such weapon made by S&W
