this is a picture i found at an estate sale  i dont know much about it but i was told it was blue boy  but cannot find picture like this anywhere signature is there but i cant tell who it is   plz help

I have 2 of these chairs that I bought at a garage sale.  I don't know anything about them and was wondering if anyone might know anything about them or be able to give me an approximate appraisal. 

Thank you!!! 

De Laval No. 12 cream separator with all the accessories

on the handle it reads "60 rev. per. min"

also reads "saves $ per cow every year"

 It's a container with a dragon handpainted on the lid. 

This is a 6 volt powered small lantern. Stamped on the bottom is: Delta Powerlite lantern. Delta Electric Company Marion Indiana.  It has some rust around the edges but all there.

 Evidently, these are two pieces derived from a chess set. Other than the dimensions and weight I listed, I must apoloize that I do not have any further details. Thank you for any help you provide in assessing their value.
