Brass Texas Air Guns body kit nelson in good shape. I bought this a couple months back with a dent in the end of the barrel. I removed the dent and it looks good now. Condition is great. Back bottle valve is steel and has adjuster hole so it's likely an Air Power asa. No adjuster internals though. Holds air and cycles but not chronographed. I purchased because I though the pump handle was for a PS-15 Marauder but it turns out most Tag nelsons used this same pump handle. Has someone's number carved into receiver? Not a phone number because it's a digit too short? Might be social security number? Stock nelson internals. Looks fantastic, great, classic vintage piece of paintball. Body is brass and painted black.
