That’s a gorgeous pair of Model 52s — the G&H work really elevates the rifle, and the pre-A you picked up looks equally clean. If you ever decide to add another variation or compare values,
GunsAmerica usually has a solid mix of 52s listed, which helps get a sense of market pricing and condition differences. One thing I’d suggest is checking the bedding and action screw torque on both rifles; a little fine-tuning there can noticeably tighten groups on these older rimfires. Really great finds — rifles like these don’t come around often.
