Dan, Brad, guys:
First, Dan and Brad: I am sure that you have copies of whatever I have on the Rawdons, since I have sent Brad every little bit of data I have gathered. But, if you want, I can re-send everything either to you Dan or to Brad, for your planned web-site.
Now, for everyone else, the following are bits and pieces of data gathered on the Rawdons, and some registration and construction data kindly provided by Mr. John Davis (Wichita, KS) aviation historian extraordinaire:

Brad:
Interesting pictures, particularly the Salvadorean machine.
But going "in reverse," was interested to know you had bought T1-15 here, in Kansas. Give a call before/when you get here - and maybe we can meet up. You have my e-mail address, phone is 316 + 685 -7929.
The photos are great, and are 'pre-delivery' shots, taken at the former Rawdon Field, here in Wichita. I suspect that the photo of the three FAC aircraft was taken on the same day as the aerial shot of the three of them in formation. There appears to be no external evidence of special fitments for armaments, but we really need some photos of the front of the wings and fuselage to see if there was anything special in evidence.
Now to the Salvadorean aircraft YS-237. The registration is in the first (?) post-war registration sequence, which was an ascending series (with a few duplicates) up to YS-305 approx (that being the highest number I have). YS-237 dates from approximately May 1955. In January 1957 - as far as I can see - all surviving aircraft were reregistered in new sequences that included a suffix/function letter. In the case of the Rawdons an "A" for 'Agricultura.' Thus YS-237 would have become YS-ooo-A. YS-300-A was still on the register in 1965. My presumption is that when you refer to YS-300, you are talking of YS-300-A - photo of confirmed date info would be most helpful.
Your N2702D T1-16S is given as a 1954 aircraft, but I have no date for the one you have bought N2700D T1-15S. Do you have exact 'dates of manufacture' of these aircraft? N2703D T1-20SD was built in July 1956. Thus YS-237 has to be TI-17S, TI-18S, or TI-19S. TI-18S became
YS-401A on 2nd July 1957. YS-400-A was registered the same day, and is given as c/n TI-25D (sic). "TI-25D" would correctly be TI-25SD, but that has a known history as N2707D and CX-AUR ((Uruguay). Also germane to this discussion are T1-22 (no info), and TI-22 (model unknown) which became YS-404A on 23Aug57.
I would like to suggest that five aircraft were delivered to El Salvador - c/nos 17, 18, 19, 21 & 22. These became YS-400-A to YS-404-A in the 1957 reregistration; and that after various accidents a 'new' aircraft YS-300-A was built from the parts available. One further aircraft, T1-27S an T1-SD N2708D became YS-448-A on 24th November 1958, but does not relate to the earlier machines. Somewhere in a newspaper or magazine report there has to be a story on these aircraft being delivered.
I would, of course, welcome your comments, criticisms, or belly laughs.
John

RE: Rawdon T-1
Message:
The three Rawdon T-1s mentioned by Brad as being supplied to the Colombian Air Force were serial numbers 8M, 9M and 10M. They received a US Export Certificate dated October 21st 1952 and the paperwork indicated they had Air Force serials 120, 121 and 122 respectively.
Another example [NOT SAMPLE!!] , serial number 7, had an Export CofA on May 7th 1952 and went to Colombia as HK-289E.
These aircraft were designed for sport, training or
crop-dusting. A photo I've seen in Jane's of a T-1S looks as though what is actually a spray tank under the belly, could be construed as a bomb!

Rawdon's ATC (Air Type Certificate) 794, can be found also in one of Juptner's books on ATCs. I
Only have two of Juptner's books, though.
