Bharpring, I really do like that buckle you've found. I think perhaps the "white" is enamel? One reason for this post, is that it is primarily aimed at newer detectorist. I wish now I had kept ALL the various buckles I've found over the years, there had been many. When you have one or two etc., seems like no big deal, but over time, if you end up with a good number of them, separate by alloy?, clean or restore as best you can, what a very cool display they might make in a frame. Wish I had done that. Consider that each buckle was in essence a "personal" item at one time, same as I've mentioned in another thread about pocket watches, another thing I often wished I had kept for the same reason. At least I DID do that with keys and marbles. Just a thought fella's, (and lady's). As far as cleaning? Man, I really do not know, if it's rust on the back, normally I would say a vinegar soak, or electrolysis?, but with the possible enamel I do not think I would chance it. Others on this Forum would have a very good answer to that question. Again, I do like the buckle.
