John — memory playing tricks on me. At the time I said:
All four glass items were hand made, blown using the same shape mould, attached to the pontil rod, then the top hand-worked to the individual shape required.
If you zoom out on the little registration number image, you will see that the inside bottom corners are almost perfect 3-D right angles, indicative of a very high standard of production. Like you, I can't see how they could have been pressed unless they were made like Chippendale bottles in two pieces and joined. But there's no trace of that. So I was probably right at the time.
Thanks for correcting me.
BTW some of the early Manchester cruet bottles were pressed, like the one illustrated on p.50 of Thompson. What came out of the press was a tall vase shape, about twice the height of the height of the shoulders. The neck and rim was hot worked from this extra glass.
