Ice cream lovely ice cream ?

Hi
I'm aware that if this is what I'm thinking it is it won't fulfil the 20th Century criteria.  

However here goes - I think this is a penny lick ice cream glass but it's so heavy at nearly 19ozs . Could that be right? Minimal scratches and unground pontil, in fact it could have been made yesterday, but would anybody bother? If not for ice cream and Victorian what could it be ?
Any ideas welcome. Thanks

That's what I've always assumed they were. The size and weight of the glass gives you the impression there's more ice cream than there really is.

Yes a tiny amount. It's the weight and the bulkiness of it that gives me doubts. Comparing it with others online

I think it just means it's older

That would be great !
