I just got my vent-figure back from ThrowThings.com
I was concerned for no reason they did a fantastic job!

They not only sell ventriloquist oriented products and props,
they offer a variety of upgrade services.

They can take a (vintage in my case) pull-string figure,
and add a new body, swivel neck, and lever mouth movement.
They can also do upgrades with moving eyes and eyebrows.

I found their materials to be very high-quality,
their work careful, excellent, and fast,
and their customer service is excellent!
Everything was shipped back safely and well packed.

If you need a quality upgrade for any of your old figures
(wood and metal parts, not plastic and cardboard)
or, if you’re new and looking for inexpensive dolls and props,
they are at:

http://www.ThrowThings.com and the owner is Marc,
a great guy with a theatrical background.

Magically,
Walt
