My Changeling won't match this exactly. I made the A and M wider and used a lower crossbar on the R. (I consider these improvements :-) I changed quite a few other things in it, such as adding a ton of alternate characters and new weights and styles.

I don't know of any available digital versions of the original under its real name (i.e., China) but there are some out there with other names such as Camp Caps if you need to match it exactly.

One digitization that matches this sample is Southern Software's 'Eyechart Display Caps SSi', which is widely available on the web.

Yeah, that's one of them. It's not very well digitized and has a very incomplete character set, but it may work for you.

Chris, support the Indie community and buy Marks font. In the long run you will be happier with a complete font.
