Maple Hunter Texas is usually a good source, but I didn't see that model listed. They might want to give them a call to see if they have it, but not listed. They are very easy to work with, they may offer a suggestion of someone else to try.
You might try this place: http://ihccw.com/decals.html. I've ordered things from them before and been very happy with them. I didn't see the exact set for a 1712, but they have the 1812, which would have been the same other than the number.
Thanks for the reply, I talked with Maple Hunter and the woman is going to get back to me. She said they should be able to come up with a set. Thanks again Matt
