It looks good to me but I can't presently compare the letter width with a known original. There are lots of un dated examples though. The font differs through time. If you have access to a blacklight, check the thread in the stitching under the blacklight. If the thread fluoresces under the blacklight, it is new, but if the thread remains dull it is most likely original.
Here's a link to show some comparison pics and a new example that has sold.
