The housing is very similar to PDC_04_03 even down to the sheet of green paper behind the plate.  DB47 has a similar housing but has not been taken out of its case to look for green paper.  FAU032 has a similar case and an embossed paper.  It seems likely that all these cases are all from the same manufacturer who inserted a sheet of coloured paper into the space for the daguerrepotype to provide an attractive contrast to the surrounding coloured velvet.  
The housing is also similar to 2007-65/20 (as far as can be seen), 1956-805/1, MFM S-6397, and bears some similarities with MLK_FH_ 02082.
