On the bottom bracket cups will be most often a thread type stamp. Report that and the seat post size if can be found.

Always a chance the fork and the frame were mated long after the two were built.
Any chance you might know some similar bikes? or any direction as to the id of the frame?at least I know its not in any way related to colnago neither ron cooper who uses card suites in his frames.
