Just updating my initial post with availability and cost of New Surplus (NS) A14 regulators manufactured by FPI in 1990 with part #1550. These are new in the original OEM packaging. Stock is currently 10 units and the cost is $600 per unit. Let me know if anyone needs a unit and I will put you in touch with the shop in CA that is stocking these. Also, if anyone knows of a shop that can overhaul these units besides FPI, and especially someone out west, please advise.
