The 27.00 fee gets you a photocopy of his application as he filled it out. The 16.00 fee gets you an electronic version sent to your email. I do not know if it is a scanned image or a transcription of what was filled in.
Since he was in the US by 1917 and born 1893 then he should have filed a WWI Draft Registration Card. There were 3 versions, one asked where born and one also asked where father born. If you do not find one it could mean he enlisted to serve as those already in the service didn't file cards. Have you found him in the 1930 census? Column 30 asks if a "Veteran of US Armed or Naval Forces?" Yes or No should be filled in. If served in WWI (as we call it now) then WW, (the only World War till then) can be filled in next column.
His birth date and if he was alive in 1942 then he should have filed a WWII Draft Registration Card. They ask birth place.
Look at the Catalog of the LDS FamilySearch.org website. They still have more microfilms and book sources you can search than they have online records so far. A LDS Family History Center will be glad to help. You don't have to be a Member and some centers have Ancestry.com or other subscription genealogy sites to use at Centers. Just call or email for the hours they have volunteers available at your local FHC.
