Featured Oil lamp base, Boston & Sandwich? Reproduction?

This was in a thrift store today. had an electrified burner when I bought it. Stands a little over 8" and is pretty heavy thick glass.
I heard there are a lot of reproductions of this type of lamps so was hoping someone could tell me if it is original or repro.

I LOVE it....would put my $$ on original, but that doesn't necessarily mean I'm correct!!

Maybe Iowa can give you an ID on it.

 

I'm no expert, I like what I see, shelf wear on the very bottom, a tinge of lavender.

 

thanks for the link. Looks real, plastered on collar. Passed blacklight test.

Thanks for looking everyone. Does anyone know what the burner was for these? Whale oil?

Looks good to me too......but I've only had a few to sell in the past. I agree shelf wear looks authentic.

 

Your lamp is pictured in Barlow and Kaiser's book on whale oil lamps, though in blue with white base. The pattern is called "Pressed Heart with Pressed Hexagonal Base". They do say that the Heart lamp has been reproduced several times during the 1900s and that as late as 1988, they were being imported.
