As to Kohler, th^ girQ the Goversment a 30jt dlscouiit# I am 8 U 3 *e Caaa does 
also* The Kohler 5 KVA gasoline drir^, 115 volt, AS single phase eosts 
$1,615*00 (list pries)* fhe Kohler 10 KVA, same l^pe, the eost is $1S45*00* 
Benee, the differsnee is pries between ^e 10 KVA and the 5 KVA is onl^ 
$230*00 (list prices),- in other words, for an additional $230*00 we have 
doable the KVA* 1 do not know present priees, bat the proportion will be 
about the same* 
Soper and X know that 5KVA is inadequate for our bare present needs, and 
we feel that the lowest that would serve our reqoirensnts w<»ild be a 10 KVA* 
We stronglj reecssmend TWO sueh tmits* While will say that these en¬ 
gines are mde for continuous service, this is not so* CoraBon sence even 
dictates that by alternating one with the other w© will have less tear end 
wear* 
Now as to gasoline eonsanpticm, I have data <m the Kohler* The figures aret 
Gasoline, pints per hour ' 
X/4 load 1/2 load 3/A loi^ ftH load 
5 m 5.5 6.0 7*0 8.0 
10 KVA 6*0 8*0 10*0 12.5 
Since I omitted some data, X will give here exactly what we needs 
10 KVA U5 Volts, A, 
*w** 
will 
that the 10 KVA ’.^ill be rated 115/230 Volts,- this is OK and preferred be- 
ease if we need 220 ac 230 volts, we have it* ihrMwtewrdaft 3-pi3a8a is OK 
bat we prefer single phase* 
We recommend, therefore, two of the 10 KVA because these will take care of 
our presMit needs, and prolmbly for a few more years* We recommend the ONAN 
becauBO we have two 5 KVA and their reoord/ is such that we know these are 
a really good make* Also, that Caaan uses Ford parts vM.eh are available* 
And next. Chichi is best acquainted with gasoline engines, and gasoline is 
readily and easily available* 
I am certain that the $6,000 balanea is conservative and X believe it is 
enough to take care of these two 10 KVA units, and the book cases* 
In yours of 9th, yon yourself forsaw that there might be a possibility that 
anotlier make might bo a lover Mg bid and be a lemon* Wa oan, I feel eertain 
got together «mofUgh strong arguments to favor the Qnan, Soper promised me 
he would send me a letter, such as you wamt* In the meantime, let ns get the 
current prices on Onans* X am not interested in automatic controls* These 
are fine, but back of my head I feel it means a lot of gadgets to go our of 
order* Soper does not agree with me* But, as long as we have a button to 
press to start the engine, what more do we need? 
How re the cable,- your Itr of the 9th,- God bless you John, you are on the 
right track, the Arctic-Des/ert-Tropic set up is an ideal approach, and X 
am dead sure you will meet with suoeess* I feel sure they will not clutter
