Commission # question

[jjbunn]

What information can be deduced about the following TR6 commission number:

1CP52xxxLP

(where xxx is a 3 digit number). From what I can tell this is a 1971 car, left hand drive (L). But what is the significance of "CP" - fuel injection? - and the terminal "P"?

Thanks!

You are correct on the "CP" as petrol injected, and "L" for left hand, have no idea what the last "P" references, nor mention of a "P" suffix in my resources.

I also have not seen a final "P" suffix letter, but the initial "1" usually indicates a Triumph that was assembled in Belgium rather than Coventry, England.

the motor, gearbox and diff have commission numbers, was there ever a commission number stamped on the TR6 chassis?
My car license papers don't have the commission/chassis number listed (only engine number) and my compliance plate is dated 1964!!! Obviously a wrong one was re-attached after the original was lost.

I don't think so, at least not a number that really means anything at all.

I guess so! Does the engine number on the papers match that on the engine? and what exactly does the "compliance plate" have on it?

The TR6's sold in the US do not have a number on the frame, but they do have it on the body. It should be on the "scuttle panel" found by lifting up the "bonnet". They also have the id on a plate riveted to the windshield frame.

The plate in the engine compartment will give you the "commission number" which is the chassis number, and paint and trim numbers.

Actually, I believe most US-spec TR6s (from about the 1970 model year on) have the commission number plate on the LH or driver's side B-post. But it's also possible(?) that Belgian-assembled cars are different in that respect; I don't know. Regardless, a car built for sale in the US originally would've had some such notation on the commission number plate and also would've had the tag with commission number on the windshield post.

Hi Andy,

On this Belgian-built '71 TR6 I'm looking at, there are two plates on the scuttle panel: one with the commission number, weights etc., and the other with the paint and trim codes.

my car was assembled in Australian by British Leyland. The compliance plates for our neck of the woods are riveted to the LH wheel arch inside the engine bay. The rivet holes are there and a 'ghost image' of where the plate was once fixed is all there is. The 'fake' commission plate has been riveted in place inside the passenger door post.
It notes the following:
CR 882
Paint 92
Trim 11
Weight (unreadable)
B.S. AU. 48 1965 (not '64 as I incorrectly recalled)
The engine number matches the license papers.
Regards
Craig

I believe that I read somewhere that cars assembled at the Maline plant in Belgium often had extra letters added to both the prefix and suffix.

Ah, I missed this follow-up! That whole line refers to a British Standard (no pun intended) for seat belt anchorages, as I recall. It has little or nothing to do with the year of the car except that (perhaps obviously) the car would be a 1965 or later model.

Hey Andy!

Real strange. You might remember the 1969ish TR6
Crypt Car has no commission numbers stamped on
it's TR4A tranny case or it's differential. I personally
cleaned them both to shiny metal and found no numbers.

I have a 1968 TR250 commission number on the engine block
were you'd expect to find it. I have a fake 1969 number
plate in the door.

I have a 1969 steering wheel, steering column and 1969 dash.
The DID have a 1969 intake manifold. Jeff Palya rid of it
during his carb rebuild.

Is there any where else I could look to find a number?

Dale, I think all TR6s -- at least "Federal" cars -- would have a tag on the LH side windshield post with the car's commission number. There shouldn't be any commission plates on the LH B-post (what does the "fake" one look like?), but there should be/have been a commission number plate under the hood (LH wheelarch, as I recall). Odd that there would be no serial numbers anywhere on the gearbox or diff. cases, though, especially since I can't think of any good reason why someone would go to the trouble to obscure or remove those numbers!

C'mon Andy, I'm sure you can think of at least one reason ! The fellows at the local chop shop probably don't know that Triumph numbers don't match...

I said good reason, didn't I? /bcforum/images/%%GRAEMLIN_URL%%/smile.gif
