Read this paragraph about the TofD gun:
Indiana Jones (Harrison Ford) loses his Colt Official Police at the beginning of the film when Willie drops it out of the getaway car after they exit club Obi Wan. Indy's had a 4" barrel and was .38 special. It had been thought that the Temple of Doom gun was the Colt New Service M1917 or possibly one of the cut down S&W's from Raiders of the Lost Ark, but new evidence and first hand information from members of IndyGear's Club Obi Wan has led to the discovery that it was a 4 inch Colt Official Police .38.
I know it's under discussion, but nothing conclusive has been made to my knowledge of it being an Official Police .38. It's a good candidate, that's for sure, but listing COW as the 'source' without checking with the administration first isn't good.

What 'first hand information' are they talking about?
In posting absolutes as read above, one must approach things like this as you would a court of law. Viewing all the fuzzy out of focus photos of the revolver that have been shown to date, can one say with absolute certainty the revolver in question is a Colt Official Police .38? I know
I can't, but can say from all evidence shown, it's a good candidate....but that's
ALL I can say. It's a best guess, and should be stated as such.
'First hand information'? 'Site your source' would be my first question if this had been turned in for peer review.
Lots of problems here, and all credited to IG. If somehow in the future it's proven NOT to be a Colt OP, COW is credited for an incorrect piece of information that COW had no say so about.
Not good.
