The lock "guts" although not EIC look good and the lock should work well enough if you wanted.
Sorry to disagree, but they did not always use what you describe as a "quartered heart". The style on my lock (whether it is genuine or a copy) is the same as that shown on Ricks lock dated 1805. The quartered version came later according to the small amount of reference I can find.
The lock itself actually sparks well, and the gun it came from has been used as a shooter in the recent past.
