tigermoth,airindia

Hello,
my friend is ceremoniously collecting various airindia miniature plane
models and is short of the miniature tigermoth which also happened
to be one of the flights flown by his father. I would appreciate if
any of the esteemed readers could point a direction to were I could
get one ? or if any one of you'll have it with them and would like to
give it for a price, believe me this goes into a genuine collection
and would be much appreciated. Thanks very much for all your help.
