Set of four and single beehive  are 3 1/2". Single Thayer baby carriage cap is 3 7/8". All mounting tabs are present, but some need straightening. All have been repainted, but metal is in good shape and not rusted out. If you know definitively what these are for please feel free to message me and I will update the listing.
