Editor: of course we will gladly help. Especially as father and son were kind kind enough to provide us with lots of useful information and specs. One thing is sure, this is a very nice T-head, but not one of the famous marque from Wilkes Barre, PA, USA...

Engine specifications: rotation: counter clockwise / Bore: 4 .5 inches. Stroke 4 .75inches / Twin camshafts / Side Valve / Roller cam followers / External Oil system; total loss? (missing from engine) / Dual Ignition: ? Magneto +? / Cone clutch / No manufacturer markings or stamps on the engine / Big ends have 4 bolts on each, which go through the rods and threaded into the rod caps with lock nuts / Rods made from bronze like material and have no big end bearing, runs in the rod material / Crankshaft mounted in the sump." Who can help?
