Tallboy Lancaster

[Jonny]

Hi ...

I've got the 1/72 Freightdog Tallnboy conversion kit and an Airfix Lancaster.  The Freightodog kit includes radio altimeter arials which the instructions say are to be fitted under the tailplane.

 

I've been trying to find reference material which shows just where the ariials fit ... I think the tailplane had a span of around 33 feet, in real life so there's lots of room for the arials! 

 

Can someone please tell me just where thes arials fit?  Also, what colour would they have been?

 

Any input gratefully received,

 

Jonny
