Dear Art Supply Company: Help Artists like Me and Make this...

A while back, I created a post about how to make a visualiser. I also mentioned my preferences for my visualiser to be separate from my easel. I talked about how there is nothing like this on the art market or art supply store. The most common you will find my happiest version of a viewfinder is in your large-ish city museums displaying these devices made most commonly in the 1700s to late 1800s.

For school, my final, I have to propose, and I can't think of any better one than my place for some company to take my renewed idea. So here goes nothing, here is my request: take this vital handy equipment from the dusty museum into the classrooms, field and studios of artist across the world. Revitalise this viewfinder and help artists across the globe make better art.
Maybe you work for or own an art company, or perhaps you want to make a business helping artists and handcraft these on Etsy. I don't know. But if you are reading this, someone could make a killing if they put a lifetime into making the best visualiser's possible.
If I were to take this to an art company, I think I may look at Sennelier or Caran D'ache (Well, cause I am partial to their paints and pigments.)
Want to check out their websites? Here are the links above. I normally attach them to the picture, but in the lower small gallery format, this Wix blog dose not have that option. Maybe this is better. Tell me your preferences in the comments below.

Or Maybe Arteza (They are affordable, steady, and seem to be a creative company always coming up with something new). Another good shout may be Mabef, as their primary goal is furnishing artists studios, art classrooms and all that jazz.

Well, anyway, without further ado, here is my proposal. Maybe one day, I will take the time and flush out this idea into a formal design and bring it to an art company like the ones above. But for now, it's just an approach. Or more like a sales pitch as to why these should be made than an actual design.
Please give it a read and tell me what you think in the comments below.
