A bit late now and kind of trival, but the statement about there being fewer IRS 4As than 250s, just doesn't seem right. The 250 was only produced for one year and according to the comm. numbers 8594 was built. The TR4A was made from Jan. 65 to Aug. 67 with over 28,000 made. The vast majority I have seen are IRS cars, which was about a $160 option when new.
I was going to make the same comment. Approximately 25% were estimated to have been live axle so roughly 7,000 live axle and 21,000 IRS so there should be far more TR4A IRS than TR250's.
