Unable to find this pattern anywhere.

i recently purchased a set of 6, of these sherbet dishes. They are all in excellent condition. They all have a stainless metal holder that they fit into. They are aprox. 3 7/8 in across x 3 1/4 in high (in the holder). 2 1/2 in (out of the holder). I have researched this pattern extensively and have yet to find any info about it. Any help identifying this pattern would be appreciated.
