The Ei tube was made in Yugoslavia. It's early 70s based on the A-Frame and getter. I've got some Ei Philips PCC88s, they're not bad sounding tubes.
Likewise, there is no visible etch code indicating the Lorenz tube was made in Herleen, at least not from the photos.
The Mullards are also A-frame from what I can make out in the photos, probably a bit better than the Yugoslavian-manufactured tubes.
From the same seller as the Mullards, 1966 Valvo (Philips / Herleen Mfg = same tube as the Amperex Bugle Boy of that year) PCC189s for $24 USD/pr. http://www.ebay.com/itm/2-x-Valvo-PCC189-7ES8-tubes-NIB-Philips-Heerlen-Holland-/390688064788?pt=Vintage_Electronics_R2&hash=item5af6d2c514
