I recently found the first picture here and when I checked my c/n 086 file I found another that had never been posted.

Unfortunately none of these photos show the 3 bladed prop that the aircraft would have had after the conversion from an H-391B to an H-395. By the time it had the first accident it had been converted but you can't really see the prop in the accident picture or the other two.

added picture as B-833 in the 4th position in the lineup above.

Unfortunately it still doesn't show the 3 bladed prop which indicates the conversion to an H-395 but you can see that it now has cowl flaps.
