At first glance none of those look like McCallum bagpipes. I play McCallum and I know several other people that also play McCallum. It is hard to say if these would be worth it or not.

There are 2 sets of pipes. Both look plastic, yet the pictures could be deceiving on this. The smallpipes are hard to identify. The drone caps stand out of the great pipes as a unusual. I would expect the ends to look like like they are on this set of McCallum pipes: http://www.hendersongroupltd.com/car...idcategory=468

Questions I would ask:
- If the pipes were purchased directly from McCallum, why is there a Pipers Choice soft case?
- What type of bag does each set of pipes have?
- What type of chanter reed does each set of pipes have?
- What type of drone reeds does each set of pipes have?
- Can you hear these pipes played before going to look at them?
