Egg boilers from the end of the 1800s

Height 26 cm. Fine egg cooker in brass from the end of the 19th century. It is egg-shaped and finished with a lid knob like a hen. Inside, it is tinned and has a holder for 3 eggs. On the plate between the 3 legs there must be an alcohol burner to heat the water inside. It is in very good condition with a nice old patina.
