Hi George and welcome to the forum.
A quick Google search suggests that the kit is still available :-
scalemates.com
oldmodelkits.com
worthpoint.com, etc.
They may be able to help with a photocopy or two ?
You've also posted here in the "Beginners Section" of the forum, so you could try broadening the search to other areas where folk may still have the original box /instructions 'on the shelf'.
Good hunting !
Dave
