I have not found any threads dealing with these so here goes.
I recently acquired this hand blown Victorian wasp/fly catcher, it measures 6 inches at it's widest point, stands 8 inches tall on its three 'blob' feet and the neck diameter for the cork bung is 1 and 1/4 inches. I have wanted one of these for many years but up to now have never found one, not even at the antiques fairs.
