I recently acquired a RI with a serial number which is over 421,000. It seems to be much higher than the usual ones and is probably one that has been assembled from parts left over somewhere in the 20's or 30's. How far did that program go in terms of serial numbers and what is the highest number recorded on these completed Rock Islands. Thank you. J. Cooper
