Notes I've taken indicate there are observed parkerized Ithacas above 893000 and below 896000 (2 that I have notes on) and that no dulites had been observed above 890000.

Here is one on GB, 894839, that says it is Dulite. If the finish is as stated, and original, this would adjust some of the historical notes I know many of us keep. If correct, this example, coupled with the abve 2 parkerized examples, would indicate that there may be a mixture of parkerized and Dulite in a transition range of serial numbers. I don't have the expertise to tell dulite vs. parkerized on photos. What does this one look like to you?
