Mark, The government is in a unique position to not limit competition by naming specific manufacturers of specialty items,particularly if the desired item is only made by one manufacturer.They get around this by writing a specification that can ONLY be satisfied by the desired componant.Sounds like a conspiracy theory,but it really isn't.They are just attempting to get what they want and nothing less(they may have their reasons). If possible,try and find a competitor who may have done a similar project with the same branch of the government(GSA,AEC,etc.).If this fails,try and make direct contact with the spec. writer,he may tell you(off the record)where to find it.
