I came across an old frame that I beleive to be a JMC. The headtube looks like it has been repaired. Was the original headtube machined on the inside or straight? Also were there vent holes drilled in the headtube that lead into the top tupe and/or downtube for welding? Any help wpuld be appreciated. Thank you in advance!

If the top tube pierces the seat tube and the end of that tube is stamped JMC it is a JMC.
