You have been saving that receipt for a long time !!
The more markings the more I like
I put them in the dishwasher before the photos.I'm jealous of all those nice clean tubes and the wonderful photography. Looking at a change in scenery soon so I can take some nice pictures.

It is a Siemens, nothing special .Does anyone know what is this one? It has "Hewlett Packard 6DJ8, Made in Germany" written on it. On the bottom "47" like some Siemens tubes have, but no gold pins. Looks like a Siemens ECC88? It has 2 stage getter but no gold pins. On the american 6922 or 6DJ8 I have that getter is flat, not like this one which looks similar to european ones. If you look in this photo under "6DJ8" there is a "≠" but there is barely visible.

My dilemma comes from the fact that all my ECC88 have a shield on top of the top mica. This Siemens does not have one, like the E88CC, but since it is branded as 6DJ8 has to be an ECC88. For example here you can see the difference:It is a Siemens, nothing special .

Here are photos of Siemens E88CC.I'll dig a little bit to see more photos of Siemens ECC88 maybe I understand what is going on. That additional shield on the top mica is common for ECC88 or E188CC but is not present on E88CC.
Later edit:
It seems you are right, the Siemens ECC88 does not have that additional layer on the top mica, at least these ones from Ebay. Strange, I was expecting similar construction for all ECC88.

Here's what has been working for me:I'm jealous of all those nice clean tubes and the wonderful photography. Looking at a change in scenery soon so I can take some nice pictures.





Thank you very much for the excellent advice and I'll definitely be trying out the suggestions soon. I've been remodeling the house lately so I'm starting to become a little cleaner, more organized and just trying to improve things overall.Here's what has been working for me:
- use Google Pixel phone for photos
- take shots in photo and also in portrait mode
- let the phone enhance the image
- crop the image to center the tube
- use a light colored background
- position the tube to let light come through it
- use side lighting, overhead lighting for drama and effects
- clean with isopropyl alcohol when needed
- use a Q-tip and stay away from markings, codes, labels
- center the labels or codes
- use various angles to show tube structure
Examples:

Backlighting washes out the image:

dark background makes it harder to see the tube:
