Rare & Unusual Engine Prefix & Numbers
Posted: Tue Sep 02, 2014 1:59 pm
I have been reviewing the Plus 2 listings and come across three cars fitted with engine numbers that have me foxed. The car details and engine numbers are:
Build date 11 Nov 69 Plus 2 unit 1990 fitted with engine no. RLK1236
Build date 12 Nov 69 Plus 2 unit 2059 fitted with engine no. RLK1237
Build date 13 Nov 69 Plus 2 unit 1959 fitted with engine no. RLK1239
The prefix RLK is a new one for me. There is no mention of it that I can find in Miles Wilkins' book. The engine numbers themselves are way off what was being fitted at the time, being mostly 20### series numbers.
My speculation is that RLK may denote some type of development engine. It would be a reasonable assumption to make that the L stands for Lotus. The numbers may indicate a short run, since they all start with what again I might assume to be a meaningless 123 sequence.
The records are not complete during this period so there may be several other cars that were also fitted with these engines. We should also bear in mind that cars were not completed sequentially by unit number, so it was not unusual for there to be substantial date differences between units, particularly in 1969 and 1970.
So dear listers, what does RLK stand for? What was unusual about these engines? Anyone know?
