My project Hunter 220 refurb' arrived and I've got a question for the experts. But first, the gun is in good condition, it's very smooth when cocking and firing except for the Gamo spring buzz. The trigger is the best stock Gamo I've had but it's going to go. Stock is nice except for a couple of very small marks you have to look for carefully. My question is, how old is this rifle? Can anyone tell from serial number on the gun? The one that has the 98 in the code is the new to me one the 04 code is from the other 220 I have. The only other difference between the two is the scope groves on the compression tube. The ones with the 98 in the code are 5.25 inches long and there is a hole that is threaded that could be for a scope stop. The other one, with the 04 in the code has 6.50 inch long groves and no hole drilled. What do you all think? Do I have a antique?
