[Milsurplus] ART-13 production questions

[WA5CAB at cs.com]

I do'nt recall ever seeing any production figures for the five variants 
(including TCZ) but it is my understanding that there were no T-412/ART-13B's 
built (from scratch).  But rather were all converted from T-47A's by COMCO 
under contract.  Further, COMCO did not design the conversion kit.  The 
conversion was designed by Pan American World Airways, Inc apparently in late 1947 
and early 1948.  PanAm had Gables Engineering build conversion kits and 
maybe do conversions of COL-52286 (ATC) and T-47's but the documents I have 
don't give a clue as to how many.  They may also have done a few T-47A's but a 
different LOCAL-REMOTE switch wafer is required.  The wafer is shown in the 
instructions but not included in the standard CDA-T kit.  I think I recall 
(I once had a numbe of the kits and a lot of extra nameplates) a third name 
on some of the plates (in addition to Gables and Comco).
