need Hubley model instruction sheet...

My dad passed away last October leaving me with numerous Hubley models all in their original boxes. Except for three,  two of which are the SJ Duesenberg model. one is missing its chassis so the other one (which he painted already as well as built the engine, complete with little wires for the distributor) I want to finish. He started it  about 15 years ago at least, but I digress. Both started models are missing their instruction sheets, I am at a loss as to where all the rest of the pieces go! If anyone has this sheet can ya' get in touch with me please? the rest of them I will keep unbuilt in their respective boxes but since these two were started, I'd like to finish one in remembrance of...thanks in advance for any help anyone can give, me
