great models ( www.greatmodels.com ) shows it as:
1/48 rmx5973 Messerschmitt Me.163B-1a Komet
they are taking pre-orders.
showing it as $19 retail, $14.50 their price
(numbers rounded for my convenience)
they have a link to a review as well. it is on:
http://features02.kitparade.com/me163pk_1.htm
they also list the testors kit for sale. cheap.
the review link is dead, and from what i have seen of testors plastic,
it probably committed suicide.
(my friend built their exclusive kitting of the P47-D Warp-o-Bolt
it had enough flash to build a second Jug. and calling the detail 'sparse' is like calling the Titanic a 'boat'!)
on the other hand, the kit is only $5. where else can you get $50 worth of aggravation so cheap?
good luck & enjoy!
