I bought the exact same kit at Michael's using a 40% off coupon and was building it for the Orphaned Armor GB. It originates from Monogram circa 1956. I first had one built by my dad in the late 60s-early 70s and built another one in the 1980s after becoming an M48A5 tanker.
The kit is nearly 60 years old, but until recently was the top M48A2 kit because it was the only one of that variant. Revell recently produced two all new tool M48A2 and M48A2GA2. I am converting my old Revell one into the GA2 so everyone can thank me for starting the conversion.
Lots of crude, molded on detail like the grunt rails and pioneer tools, over sized hinges to allow opening hatches. A decent kit, but not up to modern expectations.
