[Tigers] More insight into "Crossover" Mk1 cars

[ZForce56 at aol.com]

I am still trying to make sense if the bits of evidence I have regarding  
the sequence Crossover body Mk1 cars. I have Tiger B9473202 with JAL 562772. 
I  have heard from the owner of B9473187 that his car like mine has square 
door  corners and both cars were finished by Jensen on April Fools Day 1965. 
I have  also heard from the owner of B9473317 (presumably built after April 
1. 1965)  that his car has round door corners. A wise person on the list has 
reminded me  that Jensen received the bodies a already painted from British 
Pressed Steel and  that the JAL number is perhaps a better indicator of the 
sequence of body  production. So, does this explain the apparent 
flip-flopping of body features,  or is it more likely explainable by cars getting 
pulled from the line for repair  and thus delaying VIN assignment?
    Thanks!
