I have two K41's new-in-bag and another that has been opened but complete.
I have not built one since about 1983.
Have Semroc laser-cut fin sets for all 3 kits.
Might build one this winter.

Yes, there is such a thing as NORMAL, if you have to ask what is "NORMAL" , you probably aren't !
Failure may not be an OPTION, but it is ALWAYS a POSSIBILITY.
ALL systems are GO for MAYHEM, CHAOS, TURMOIL, FIASCOS, and HAVOC !
