Please read the notes below.

**07/28/2015** - Update - It is with great sadness that I bring this news.
Both my father and my wifes mother have passed away.
My father on July 15th and my mother in law on July 23rd.
This has caused a delay in the house sale, so we are starting over again with that now.
It's back on the market as of yesterday... I hope it sells quickly, we are all packed up and ready to move.
That means all equipment and parts too.... Sorry for the delay.
I will keep you all posted as things progress.   

06/14/2015 - It's time to move again, We will be moving closer to Dallas and hopefully to
a more permanent location. The shop is being dismantled to get ready for
the move, I be out of action for at least 6 weeks from the date of this post.

Watch this space, I will let you all know as soon as we are back up and running again.
As usual, all orders currently on hand will be completed and shipped prior
to the move. Sorry for any inconvenience this may cause.

NOTE: The 850 Store will no longer be exporting parts outside of the United States.
                                         Due to the difficulty of obtaining parts, The Kits and Parts section has been drastically Reduced.
