Damn that looks good.

Someone finally appears to have purchased the $450 M50 from eBay that I'd been watching for months without a single price reduction. Oh well.

I will post it again after bleaching - trying liquid hydrogen peroxide without UV, but heated to 33° centigrade / 91.4° fahrenheit. I’ll use an aquarium heater, and that’s it’s highest setting.

Anyone an idea on how to remove and reattach the sticker before and after the bleach? Heat from a hairdryer, n-hexane, or should I try to protect it?

I'd guess a little gentle heat to take it off is the best, but I've never actually tried. Trust a more informed opinion!

The underside doesn't look too yellowed anyway, You might just want to bathe the top shell.

came back to thank you for that aquarium heater tip. works super well and doesnt need direct uv/sunlight.
cool board tho, i watched one a long time but the 150€ was a bit too much for the curry color.

edit: no post without pictures. here is my unicorn penor blue pkb-1101 (dfk191) with alps mount beige clicky smk.

Somebody else's...of course.

Slightly less unseriously, do these have printed or doubleshot caps? The beige DFK-191s came both ways.

yes im aware of the flesh colored penor! the caps are thin doubleshots but colors are pretty off in the picture. my phone camera tries to correct the blue into a more grey color unfortunately

Thanks, it looks much more appealing in that photo. And the doubleshots sweeten the deal even further. Nice find!

i plan to make a dedicated post or wiki entry when i solved the cosmetic issues (mainly the bad yellowing), otherwise condition is pretty much unused. very happy that i got my hands on one!

If you do the hydrogen peroxide thing, either with the full retr0bright or just alone, check on whatever you're retr0brighting every 30 minutes to an hour. Retr0bright is very good at turning things that used to be white into a brighter white, but it also bleaches color out quickly. Also, when you're checking, you need to take the part out, flush it with water and dry it. I've had a couple cases that looked great in the tub o' retr0bright, but looked terrible after drying.

I'd strongly recommend trying retr0bright out on broken key caps or some random grey modifier keys before trying on the Penor / other colorful keyboards.

this is exactly my fear.
im using 0,5-1 liter of 12% peroxide solution for each case, filling up the rest with water so its fully submerged. the results so far were pretty good, but its slow (takes atleast 2 days) as i dont use direct sun/uvlight. but these were all grey cases...

Just take it slow. No need to rush.

One of the really big problems with retr0bright is if you have a keyboard that's patchy. I've never been 100% successful in masking off areas with waterproof tape to only get the patches de-yellowed. I can also say that I think I have done all of two close-enough-to-perfect retr0bright sessions on Apple keyboards (Standards and AEK IIs) out of maybe 10 keyboards. The former is just difficult. Most of the latter ones I've seen look like a carrot, but have the big rectangle of brightness around the function keys where the plastic overlay for the function keys used to go. I just retr0bright until the color is uniform, which is generally pretty darn white.

I just tried painting one of my Apple Standard top cases, too. Granted, it was my first time, but I really did not like the result.

Nicely dressed for an M122. Always love multi-colour legends, and the function overlay looks good on it.

What kind of switches are those? Also what kind of keycaps are those? I mean the profile looks like SA but I've never seen such a mount on keycaps.

they're oak full travel membrane. they're original SAs, i think. I'm not sure if the mount has a name, but they have shown up on other switches as far as i'm aware, so they aren't specific to this switch. they seem to fit a variety of vintage switches, as far as i'm aware, such as smk vintage linears.

Stellar job! Is this just the lighting or did the legends also get affected (they seem a little bit faded/transparent somehow)?

Unfortunately, the legends of the light grey keycaps seem to have faded a bit. The legends of the dark grey keys haven’t been affected.

Unfortunately not. I had to dilute the hydrogen peroxide since I’ve used a big container to accommodate the keyboard case, and didn’t kept track about how much water I’ve added to the solution. The result could have been approximately 3% H2O2, but this is a rough estimate at best.
My first attempt to use only heat to support the chemical reaction was a failure; either the aquarium heater I’ve used hadn’t enough power or the circulation wasn’t enough - the solution became only lukewarm at best. So I had to switch to plan B, and used UV/sunlight; after approximately 3 or 4 hours the result was pleasing enough for my eye. But this time depends on your location, time of day, intensity of the sun, cloud cover, etc.
