Ben, it is not my Excel spreadsheet. It is authored by another member. Consider joining that thread to discuss it further. That is why I included the link to the other thread.
My understanding is the use of the Federal terminology came after your car was manufactured. The Federal terminology is not just the market a car was sold in. My understanding is it refers to a specific model introduced with VIN 50/0857 to the US and the body mold was extended to other markets with VIN 50/0929. Your VIN is somewhat lower/earlier, and therefore not a Federal model even if it was originally sold into the US or Canadian market.
We (as in folks in North America when these cars were new) did get the Lotus Plus 2 prior to the introduction of the Federal model. I have not seen these referred to as Federal. Rather, I have seen them called Early cars. Perhaps part of the problem is the older model does not get officially re-named when a new model is introduced, so really it was originally simply known as a Plus 2.
As I say, I could be wrong, the naming of Lotus models is not an exact science, but there you go. One thing for sure, if you refer to your car as Federal you will probably get some confusing answers.
The other thread can probably provide you a more complete list of Federal features. After all, that is part of what he is trying to construct. It isn?t easy, as most of us only have detailed experience with one Plus 2, or in rarer cases maybe a few cars from the same region or market.
Here are a few items present on my car that might help with identification. Check the Robinshaw & Ross list and you can see some were introduced as running changes over time.
- Generally left hand drive.
- Dash switches are flat rocker style.
- Trunk/boot lid latch uses a remote cable.
- Somewhat different door cards.
- Revised window frames.
- Different exhaust (with no pipe bends under the trunk).
- Different pedal box.
- New steering column.
- Dual brake circuit front and rear with two brake boosters and a failure light.
- Negative ground.
- Fail safe headlights.
- Stromberg carburetors with cross pipes to the heavy cast exhaust header.
Some modifications occurred as running changes. Whether these were applied to Federal, Domestic Market, or both I don?t know; that is the topic of the other thread and the reason the author is creating the spreadsheet. Rather than type out a further big list of running changes, check over in the other thread for a scan of the Robinshaw & Ross Plus 2 Production Milestones I posted and join in the conversation.
If you have the WSM, have the diagrams, and know which one applies to your car, I am sort of puzzled with your continued questions? If it is simply a mater of trying to confirm your model ID, the other thread will hopefully be helpful.
HTH
