Thanks Roland,
I was just doing something similar the other day with some old moon sights I took a couple of years back. What was interesting was that I didn't recall the lat/ long where I had taken them so I used two different whole degree intersections for my AP that I thought to be closest. I'd already subtracted the 15' and all the LOPs plotted pretty close, the main error was IC* that I hadn't quite worked out at the time. Once I plugged that in everything fell into place and came quite close to the actual location. Using the 2 different APs meant that some of the LOPs were plotted towards and some away so once I adjusted the amount of error and corrected for it, that moved them all in the right directions.
I don't think I've yet sighted the moon using an AH, that will be on the next clear, warm night with the Davis Mk15.
*When I first got the bubble sextant the mirror arm was loose on the axle. After a number of adjustments it's still off but gives a usable reading.

I used to be a normal person, then I discovered how to locate myself on this planet using a star.
