I agree it's something of a gamble buying sight unseen there, and won't buy unless I've had the items in hand. I won't pretend to be the most expert appraiser who could look at stuff for you, but I have wall and bore gauges, can take a few photos, and am happy to be guided about what elements you'd want looked at and what you'd want to see. I'll be trying to get there for a look, as there may be the opportunity to fill a hole in my "accumulation" (who am I kidding?! I'm a collector now!) with a modest representative example. Flick me a PM and let me know what you want me to look at.
