Whoever built this really went in for stamping numbers! From what I can make out the numbers on the forkends do not match with those on the dropouts, correct? Yet I think most likely these are still of a frameset and belong together, but just due to the common style(s). Also cannot make out what the stamps are on the steerer but these also seem different to any other on other surfaces, can you note what those numbers are (or zoom in closer)? The one other detail that would be clinching is if the tips of the fork blades ALSO have the pointy treatment seen on the stay ends (on DOs) but sometimes the forks get built by an apprentice in the shop while the "master" builds the frames.
