This romantic and fascinating pair of cherub brooches joined by chains probably served to hold a Victorian lady's train -- gathering it to the side or into a bustle for dancing. It might also have been used as a chatelaine, from which various articles in frequent use were suspended by small hooks (e.g., keys, lorgnette, dainty scissors and such).
Whatever tricks it performed in the 19th century, it's a obvious treasure today -- perfect to secure your favorite shawls, scarves and cardigans. Alternatively, you might load the chains with charms and pin the festoon anywhere -- or let the item fulfill its original function as a bustle pin for a wedding or evening gown.
Of silvered brass, showing only minor losses of plating, the brooches feature two adorable repousse cherubs or angels, each with the good old open C clasp indicative of great age. The larger figure is 2.5 inches tall, while the smaller is an inch tall. They're united by three 8-inch chains of a silver metal brighter in color now than the pins, but those can easily be polished to match if you don't mind disturbing the patina of age. It's possible the chains are later replacements, but they're certainly not modern. My guess is that they're original, made of a material chosen to be sturdy in use.
