MCG is doing just fine.
Your LHS has to order new things from MCG, or else you won't see anything "new" there. The MCG web site lists all the newest stuff that has been produced. For Bob to produce photoetch for new kits, THERE HAS TO BE NEW KITS! The few new kits, such as, Magnums, Charger R/T's, Model King limited reissued race car kits,etc. do not lend themselves to photoetch sets.
It is hoped that the 68-70 Nova photoetch will fit the new Revell '69 Nova kit, but Bob has to have the kit in hand before he will know for sure. He doesn't get advanced test shots like he used to, many years ago.
A few years ago, on the old Hobby Heaven board, someone typed that they heard that MCG had a big layoff!!!!!! He must have layed off the Palmetto bugs in his Florida garage, because MCG is a one-man operation.
