How "stable" in term of numbers are your airgun collections ?

Mine seems to flutuate "big dipper style" either going up after a period of fairly intense acquisitions or reduce if I want something say expensive be it another piece of shooting equipment OR anything else for that matter !

At present I seem to be off-loading a few in preparation for buying another bit of "pricey kit" and a possible house move !
All in all, my collection is never really stable.
