It has all the earmarks of an early 1970s reproduction tub...that includes a mix of M38 and CJ3A features.
The owner told me that the man that had restored the jeep wanted a M38, the problem here in Argentina is that there are only 3 MCs, and its cheaper to buy a new Ferrari than one of those jeeps. So, he decided to convert a CJ3A to MC. It could be a repro tub, however I never see that stuff here in Argentina. I talked to this guy who had restored this jeep, and believe me, he never would use a repro tub, his hobby is to restored old vehicles.
So, I don't know, maybe it could be repro tub Tim, maybe not. However, thank you for all your help. Your OD looks great!
