Well Bob Z. finds bargains at garage sales. This is what I found this evening picking up some plans that I had laid on my scrap balsa box. It is the "Dynamic Models Tech-Tip Manual". Had to have been in 1958 or 59 when I got it from them. If you look close there is no zip code and names for the phone number instead of area code. The index shows:
1. Catalog Sheet showing the Holland and Johnson engines.
2. Tech Tips A thru f or No. 1 thru 6.
3 Parts Price List for the engines
4 Parts Price List Johnson Flying Lines.
Idon't know if posting on the bay would get a decent price or not.
