There are many manufacturers of accordions. These include Acme, Alpha Music, Bolero, Bomar, Chanson, Da Vinci, Duma, Embassy, and Excello.
Hundreds of companies have manufactured accordions over the years. A few better known from the past and present include: Hohner, Scandalli, Excelsior, Bugari and Acme.
I have one also. The only information on the instrument is "Belcanto", "Made in Italy" and "L/606/7" I can't find any record of an accordion manufacturer called Belcanto.

The website simply named Accordion-Doors has the largest selection of accordion doors. When looking to shop in-store as opposed to online, though, Home Depot has the largest selection.
A good place to find an accordion wall lamp is on HomeDecorators. They are a good site to use and have coupons that could save you money. If HomeDecorators is too expensive for you, then you could go on Amazon or Ebay.
The best way to find the manufacturer is to visit the store that the appliance was purchased from and give them the manufacturer code of the appliance. They should be able to provide contact information for the manufacturer.
Usually, you can find the name of the company that made the accordion just above the registers on the right hand side of it. So between the keys and the bellows. There usually won't be a logo, but rather, just the company name.
To find a manufacturer, type into Google the words: manufacturer+the product For Dacor Kitchen products, you'll find IraWoods is the manufacturer. See: http://www.irawoods.com/Shop-by-Brand/Dacor?gclid=CPzJ-6C8qp8CFaM45QodrWi60w
contact the manufacturer. If manufacturer is unavailable, you may be out of luck.
Find the name of the manufacturer, model, and serial number of your unit. I recommend contacting a local HVAC company with this information. They will be able to contact the manufacturer to find out the efficiency. You can even call the manufacturer directly and they may be able to get you the information you seek.
Google the manufacturer's name. k
