Well aren't you a clever boy!
However, there's no need to go to all that trouble - simply hold Ctrl while turning the scroll wheel on the mouse to zoom it in the web browser. Or Ctrl and the plus/minus keys. Ctrl+0 to reset to 100% when done.
Obviously I did zoom in, but know better than to state absolutes based on a low-res photo on an internet forum. Especially a photo that wasn't taken by the OP, who hadn't actually collected it at that point in time. Though he did subsequently mention "deep mauve resistors", which swings the odds back. Whatever, I was 95% convinced, but have been jumped on too many times over the years.
The other ones look like Iskra - also carbon film. I'm 95% convinced of that

Also very reliable in my experience. My earlier comments about high-ish values and high-ish voltage still applies, however. Those Piher types were notorious for failing in Telequipment 'scopes, though to be fair to them, they were seriously over-volted, and lasted for decades before they'd risen in value enough to cause noticeable problems. They switched to Mullard (now Vishay) VR37 later on, and those remain a good recommendation for high voltage situations:
