Yes, it is a regular Strathearn item.
This design was probably made during all of their paperweight making years.
Main clues are "chunky" white (grey) twist canes and a fire polished base. However, both of those clues are not specific to Strathearn weights and those features are not always evident in their items.
For lots of info on Strathearn weights see Richard More's website I linked to in your Strathearn Aurora weight thread.
