Uncredited Actors: It’s a little indistinct in the syndication print, but Don Anderson plays a uniformed officer who speaks to the plainclothesman at the junkyard. A little later he takes a piece of paper from the Police Chief at the scene of the crime. Submitted by gracenote 8/19/2011.

Although familiar to PM fans from his seven episode appearances, Neil Hamilton is most familiar world-wide from his role in the still-syndicated campy Batman series, in which he played Commissioner Gordon. Submitted by cgraul, 11/1/11.

Barry's Car, later referred to as an "old sports car" by a witness in court, is a TRIUMPH TR3 (produced 1955-1962). This lower-price sports car is the right type of car for a '60s Drifting Dropout but it wasn't really that old since its exterior door handles and relatively extensive trim (eg, fender mirrors) identify it as '58 or later (TR2s and early TR3s only had handles on the inside of the doors). Barry's car is what was popularly called a TR3A (1958-on) and might even be the last year's TR3B ('62). See Ep#178 Trivia for the design progression of the Triumph "TR Series" 1953-'76. TR2s and all the TR3s looked somewhat similar and can be misidentified. See this TR2/TR3 Spotter's Guide.

• A 1956 upgrade of the front brakes from drum to disc-type made the TR3 the first-ever British production car with front disc brakes as standard equipment, yet
• TR2s, TR3s and TR4s came with a hand-crank ("Starting Handle") as a standard toolkit item for starting the engine in case of battery failure! You can see the guideway/insertion point in the bottom-centre of the grill/front air intake of these cars. Very quaint, Wot?

A TR4 appears in another four episodes; see Ep#213. Submitted by Gary Woloski, 6 Jan 2012.
