What would this little tank go to?

This came in an auction lot of dollhouse items. But it isn't anything for a dollhouse. I've seen larger versions that were fuel tanks for heaters or something similar.

Any idea what this little tank is for?

Thanks!

 

Miniature hot water bottle for a bed, I'd say.

 

It's not sealed. There are the 2 holes in the brass cap.

 

You'd not fill it if it were a mini one for a doll's house. The real ones had rubber bungs. Yours is missing its wee handle.

 

That certainly looks like it. Thanks!

 

Some are sold as dollhouse pieces and others as salesman samples.

Call it a "Salesman Sample" - they are usually more expensive -

 

You're very welcome. I've seen the full sized ones a fair bit - that baby one's cute. They get filled with sand and used as doorstops sometimes.

I mistrust that whole sales sample thing. I think sometimes such tinies were little novelty giveaways tho'.
