Help with Lantern #2

This was a gift.  No railroad markings.  The only identification is on the porcelain wick that states "Sherwoods Limited Sounds". Google search shows it's British,  but no confirmation that it is related to the railroads or any indication of age.

It has a fixed handle,  two clear lenses, along with a red filter and a solid plate to block a lense.  There's a box bracket on the side to hang it from.  It's pretty heavy. With all the information learned on the other Lantern post, I thought I would try to find out some info on this one.
