N6836 —

Actual registration number is NL6836 but I can't get FlightAware to take it.

Nice pic, Tom! Don't worry about the N number. It is correct without the "L.". See the following from Wikipedia:

An older aircraft (registered before 31 December 1948) may have a second letter in its identifier, identifying the category of aircraft. This additional letter is not actually part of the aircraft identification (e.g. NC12345 is the same registration as N12345). Aircraft category letters have not been included on any registration numbers issued since 1 January 1949, but they still appear on antique aircraft for authenticity purposes. The categories were:

C = airline, commercial and private
G = glider
L = limited
R = restricted (such as cropdusters and racing aircraft)[8]
S = state
X = experimental

Thank you for the information Greg.

You're welcome.
