I have these for my dinner periodically.

The above information should give you 5 numbers (these may or may not be single digit numbers).
The first number is A, the second is B and so on.
The final cache is (as of 14/2/17) back where it started at NORTH 52° 01.0(E-A-7) WEST 000° 30.((B-C)*A)-D+8
This cache is not at the published coordinates - even I wouldn't put a cache in a pig sty on private land!
This cache should contain the start point for Piggin' Smelly. But, they are currently missing from the cache. Sorry.
This cache may not be suitable for vegetarians.
Congratulations to Riley54 on being First To Find and also to We do checks and cache on being first to solve
