I was able to do a British Motor Heritage factory visit way back in 2010. This is actually the British Motor Heritage Ltd. factory located in Witney, Oxfordshire. My focus here is mostly of that as an MGB tourist.
Getting A Tour
You to can do a factory tour in groups up to a maximum of 16 people. See the British Motor Heritage Ltd. website for all the details.
My fiend Robert had made all the arrangements. He planned in advance for our visit with Martin Davies of BMH. The factory is located on an industrial estate area of Witney and isn’t near shops or the town centre.
Arriving at British Motor Heritage Ltd.
On arrival we met Martin and chatted for a while to get the history on BMH. Covering how it was formed, changed over time and has acquired other relevant businesses, such as TEX Automotive, which remain separately manage subsidiaries. TEX is the maker of many things on British vehicles. They are, perhaps, most widely known for things like wing/door mirrors and wiper arms/blades.
We also covered off safety things. This includes information on whether you have a pace maker due to some strong magnetic fields within the factory! Just in case you’re not familiar with British Motor Heritage, this is the company that acquired the original MGB tooling and equipment. They are able to make original factory specification parts i.e. those that people talk about as “Heritage panels”. They do plenty of other work as well and produce Midget/Sprite, Triumph and original Mini parts to name just a few.
Archives & MGB Welding
Our first stop on the tour was the archives room. The BMH folks have accumulated lots of original documentation and manuals for the British Car industry. A scary amount of paper in there. It is organised very well. As we moved into the factory area we quickly passed shelves with parts available and ready for purchase.
After the parts shelves we came into an area where the rear end of an MGB was being welded together. This was both fascinating and a bit weird all at the same time. Weird only because we can see a brand new MGB rear end being built. They are using the exact factory tooling and equipment. Just as would have been done before being sent to Abingdon in the 1962-1980 time frame. It took me a lot of pictures to catch one with the sparks flying. But I got it eventually and I also captured some video of this.


MGB Fuel Tanks & Other Parts
After this truly fascinating start we turned the corner. Now we see some MGB fuel tanks being made. Again these use the original tooling. I noticed that these had the internal baffles in the tanks. Unlike many of the aftermarket petrol tanks. So, if you’re wondering why your petrol gauge moves around when cornering etc., it’s possible that you have a tank without the originally designed baffles in it.
It’s at this point the size, scope and significance of what goes on is this place seems to hit you. I started to see almost every part imaginable. Floor pans, rear wings and parts bins just full to the brim. All that stuff you see in the parts catalogues are right there in front of you.
We then came across a complete MGB body shell. Here is a completely original full body shell sitting in front of me in raw metal. This truly shows of all the welding and joins. Then you start to comprehend the enormous task that putting an MGB together involves. No robots, all put together using jigs, tooling and welding by people! Parts get finished by hand – all of them! This takes a bit of getting your head around; at least it did for me.


Factory Tooling On Site
Before heading up to the 1st floor we popped outside for a few minutes. Here I caught a glimpse of all the tooling that BMH have available. It has to be stored outside as they simply don’t have the room for everything. They rotate the tooling needed based on what parts they needed to produce. Obviously our timing was good as we saw MGB parts in progress. We also saw people working on Mini boot lids which were also being finished by hand. The tooling is somewhat protected by the containers. These have been obtained and modified to have one side open. This affords the tools some protection from the weather. The tooling also gets some preparation to protect it while it will be outside.

More Welding
Up on the 1st floor we had the opportunity to meet 2 BMH workers. They are producing MGB front wings. Very kindly slowed down and talked to us. The workers talk us through some of the steps involved in creating a front wing. I hadn’t thought about the wing being 3 separate pieces of metal. But it is and it’s all placed together using the jigs (everything seemed to be orange). Then welded by hand. This is again extremely labor intensive. At least with the original factory tooling and welding equipment the BMH people have the same capabilities as the original manufacturing staff did.

Given that some of this equipment is 50 years old it’s still going strong. It is well maintained. Alternatives to the original equipment would be possible. But having the original kit it makes the process as straight forward as it can be. For example, in this video you see some 50 spot welds being done. This is part of the wing near where the headlight is mounted. The workers noted that they could do 50 spot welds without this specific machine but it would be a lot harder!
Concluding The Tour
Our tour continued and we saw the complex arrangements and rows and rows of storage bins that went from floor to ceiling and had special pathways designed for the folk lift truck to work along while managing the parts inventory. We also went through the TEX Automotive section of the building and saw a lot of the wing mirrors and wiper blades/arms.
I was a little more intrigued here. Following an article in the North American MGB Register’s magazine The MG Driver, on originality, I was thinking that the wing mirrors on the 77 may be replacements vs. originals. However, a quick look at mine on the 77 do indeed show “TEX Made in England” and a number 1202 on the underside of the mirror glass holding section, maybe I’m still more original than I thought!
