Thanks Seth...I had reviewed the instructions and drawing as you suggested. I like the suggestion about the toothpick applicator & minimal glue. As for contacting the manufacturer in the event of a bump or missing pieces, I'm afraid that window closed decades ago. The kit was manufactured by an early incarnation of Weaver Model Trains; I believe Bob Weaver's endeavors started with The Quality Craft Models Line. The kits appears to be complete and unmolested by the previous owner(s).
Thanks All & Best regards,
Tom
