Wilson,
The OP quoted a rule about COTS and I agreed with the definition. (I have to) I further added a quote from the pneumatics rules to supplement the OP quote. If a part is custom order from one manufacturer but "off the shelf" from another manufacturer and you know it, why would you custom order the first part?
Many manufacturers are choosing to make everything in their line to order. Allen Bradley does this with pots and Globe Motor has gone this way with their motor/gearbox line. If that is the case with a specific manufacturer, then it would seem nothing is custom under the definition. Does anyone have a real part from a real manufacturer that would be a good example for this discussion? Hypotheticals are getting us no where.
