In need of help with research for this camera

[nifity50]

Hello all, 

I am currently in a heavy research binge on this 1955-1958 Mansfield Holiday Meter Matic. I have sources that make me believe that this is a possible Royal Camera Co. product. All I know at the moment is the fact that it is a possible Royal Produced Camera but was exported to Mansfield as a rebadged asset. However, I do have one source saying this camera was not produced by Royal but I have a couple that allude that it is. Any help is greatly welcomed!
