I found an old (1987) stock certificate of a pink sheet company that I was given, but I can't seem to find any info on the company, Hydro Power Development, Inc. Colorado, which probably has changed names, merged, or gone out of business. The trading agent is Mountain States Stock Transfer Agents, Inc does not seem to exist anymore. I do have the cusip number but do not seem to be able to find out how to look up old numbers, or even if it would help. If I knew the old trading symbol I might find it that way, but tried all the obvious with no results. Any helpful suggestions would be appreciated.
