as to (1) given the location of the FISPA pump, you can eliminate motor tipos 105, 110, 111, 119 and 129. So that leaves a tipo 131 (500 TR/TRC) or the 2.5 liter version for the 625 (is there still a 625 motor in existence whose whereabouts are known?). for (2) - a pure shot in the dark - is it the motor to 0706MDTR that ended up in the Lees collection? for (3) - if it's near Virginia - that shoots my answer for (2) . . . you got me!
