Rose tinted glasses is often the cause of reminiscing over past guns, it's often not the gun you miss, but memories associated with it, perhaps from your youth
I've done it myself, I sold a Webley Vulcan years ago I had as a kid, missed it and bought it back a few years later from the purchaser as he was giving up air guns. I kept it for about 6 months, it never fired a shot, and I sold it again - still miss that gun
