Vintage Dacor R-2 Double Hose Scuba regulator, Serviced, Very Rare!

Description

Very nice, very rare Dacor R-2 2500 series double hose regulator, serviced and dive ready.
Chrome is VG/excellent, inside and out. Label paint is intact and in great condition. This regulator is lightly used. Please expect minor cosmetic issues from 60 years of use and storage. See photos for documentation of slight imperfections. Ding in front is marked with red arrow.
This reg has the correct domed OEM diaphragms that are very pliant and supple. They might be NOS, but we'll call them used.  A new mushroom valve has been installed in the exhaust diaphragm. The HP diaphragm is OEM, but in great shape. The LP seat is OEM, and was resurfaced. The IP was set with a custom adapter (see photo of an R-2 regulator being set).
The hoseloop consists of a very supple and flexible 1" mouthpiece with new silicone non-return valves, and new hoses.
