I know about Delair, I have Harry's LONG Range set in mine. 67g.
It seems to me that part of the 170B for sale was listed as having Atlee Dodge tanks, maybe I just read it wrong.
I suggest if anyone whishes to do Harry's tanks that the only do the EXTENDED range verstion. It is 15 gal more total. and a LOT easier to install the the LONG range tanks I did.
I looked into the flints but did not want to have them electrically operated.
Did not want all that weight on the ends of the wings.
The Delair tanks are a "stock" process format, Just bigger.
