Hi Roy, I have been thinking about this too. One solution might be to prefix the ID for each piece of equipment with a code;
Site = St
Location on site = Lo
Stand =Sd
Floor =Fl
Broad Box = Bb
Crown Board = Cb
Roof = Rf
Then you can quantify any hive, starting from the ground up, eg St01,Lo03,Sd09,Fl05,Bb90,Cb87,Rf10.
If you added the Queen, Qu, then it would become
St01,Lo03,Qu06,Sd009,Fl05,Bb90,Cb87,Rf10.
If you put in a Jenter Kit, Jk, in the third frame of the Broad Box then it would become
St01,Lo03,Qu06,Sd009,Fl05,Bb90,3Jk004,Cb87,Rf10.
By having a table for your equipment and a table for equipment history, just recording when a bit of kit is moved and to where and when, it would be possible to filter by last time/date and 'see' where all your equipment is. If you filter with Site/Location you will see all the equipment that has been there.
Simples
Now to get it to work.
