We purchased a 96 15bbl, that was "mothballed as well. Ours was completely gutted and in a storage unit, but we were patient and experienced enough to piece it back to working condition. Check the boiler coils for rust through and pressure test. Check all inlet and out let ports for corrosion as well as the steam supply lines. Probrewer can supply you with all additional support help on the valve seals and electrical. Please let us know if you have any questions good luck and congrats on the future purchase.
