OK, did a little more research on alligator gar.
Near as I can tell, after a little more cursory research:
A. First off, as for the fish that is the subject of this thread, as jbadams66 pointed out,
IF that link he provided is to be believed:
-it one was shot in Sam Rayburn Reservoir near Lufkin, TX, in 2005, not at Broken Bow lake, in Oklahoma.
-it's a real fish, but it was 244.5 lbs, not 327 lbs, and not the world record. It *would* have been an Oklahoma state record, had it been from Oklahoma.
As for actual records....
B. First, as for Oklahoma records:
--In Oklahoma, the largest unrestricted (bow, snagline, jugline, etc.) gator gar was in fact caught this year by snagline in February 2006, at 184 lbs, 3 oz, in the Red River, Love County, Oklahoma. I suppose it's an Oklahoma fish only because it was pulled into the OK side, not the Texas side, or the angler was from OK - dunno. The article at the wildlife dept linked to above sort of implies it was line-caught, but it wasn't; it was snagged.
--In OK, the largest line-caught (rod & reel) was in the Red River, July 2002, and it was 180 lbs, 7 oz. Also could have been a Texas fish had it been pulled in to the other side - I dunno.

C. As for national/world records:
--The world record unrestricted (including bowfished) alligator gar is pretty hazy it seems - it is widely-reported as a trot-line or bowfished 302 pounder, but it's reported to have been from (1) the the Nueces River, Texas, (2) Vermillion Parish, Louisiana, or (3) Rio Grande River, Texas. The Vermillion Parish, LA, trot-line story seems to have the most traction, but in any event it's pretty nebulous & weak, seems to me. There is also reported 356 pounder from Horseshoe Lake, Arkansas, from 1931, but this seems to be considered an unverified one as well. The most widely-accepted verified unrestricted record is a 290 pounder from the Rio Grande River, Texas. Also, apparently, the great naturalist John James Audabon reported an alligator gar that weighed 400 lbs, buth this is also unverified. Then, there is also this picture:
http://faculty.evansville.edu/ck6/bstud/hugegar.html
which is captioned "Alligator Gar, Moon Lake, Mississippi, 1910", and looks to be 10 ft long, but no weight is claimed. Likely it would be over 300 lbs, however, given usual length-to-weight ratios (for example, the supposed 302 pounder from Louisiana is reported to have been 9 ft, 8").
--The official world record line-caught is unquestionably 279 lbs, 0 oz, but it's variously reported to have been either the Trinity river or the Rio Grande river, - either way, from Texas, in 1951.

The 'clackamas' link there is the most in-depth and interesting one on big gar. Who knows if it's the most factual.
The mis-understanding between the e-mails taught me a valuable lesson about the enternet and honesty, that is, basically, there is no honesty on the enternet.
Glad you learned a lesson; too bad it was the hard way. You 'old-timers', if I may call you that, are doing better than most just to *get on* the net!
