These Circa 1950's registers are remarkably heavy duty. This particular one is one of a kind, but the red and silver standards can be fairly easily procured. The tune is fairly complex. I scored this for $35 on an eBay "buy it now," one of my luckiest purchases.

After extensive debate among my colleagues at work, my friend Vicki suggested that the very strange song that this register plays is Mairzy Doats which you can hear the audio version if you do a search on google. I've never actually heard, or heard of this song but I think it's a generational thing from before my time. Here are the words:

Mairzy doats and dozy doats and liddle lamzy divey
A kiddley divey too, wouldn't you?
Yes! Mairzy doats and dozy doats and liddle lamzy divey
A kiddley divey too, wouldn't you?
If the words sound queer and funny to your ear
A little bit jumbled and jivey
Sing, "Mares eat oats and does eat oats
And little lambs eat ivy"
Oh! Mairzy doats and dozey doats and liddle lamzy divey
A kiddley divey too, wouldn't you?
A kiddley divey too, wouldn't you?

You can see the silver standard version in this 1955 Top Value Yellow Stamps catalogue (like Green Stamps).
