Comparison of a BFNY SN#4 to a BGM blotout, looks like a match ! The BGM blotout can be found with 1 or 2 dots on dome ... Interesting to note :: the BGM blotout is actually a tiny bit bigger than the SN#4, so maybe the SN#4 was a replacement mould for the BGM blotout ?? also it still has a "dot" after NY ........
