@PatrickBaines4 Here is that Spitfire List

Mk1 (Battle of Britain) Merlin engine 3 blade prop
Mk 5 (first with clipped wings version) Merlin 45
Mk 9 (4 blade propellor) Merlin 61?
meant to be interim model using the Mk 8 engine in Mk 5 airframe quickly thrown together to combat the F190A that outclassed the Mk 5. It went on to become the version built in greatest numbers
Mk 7 High altitude version (like Mk 6) with extended wingtips. 4 blade prop
Mk 8
Pinnacle of Merlin engined versions. 4 blade prop and first with retractable tailwheel. Used in Far East Theatre and by RAAF (and by USAAF in N. Africa/Sicily) while Mk 9 used in European Theatre
Mk PR 11
Photo Recce version used by USAAF in Europe
Merlin 4 blade prop. Deeper oil cooler to chin
Mk 14
First major production version with Griffon engine. First with 5 blade prop. Longer nose for new engine and wider stabiliser tail. Full & clipped wing version. a FR version. First with bubble canopy
Mk 16
Mk 9 built with American Packard version of Merlin

Clipped wings, bubble canopy, pointy tail

Recce version with Griffon . 5 blade prop
Mk 21

First with the brand new wing. Much bigger tail
Too late for WW2

(Mk 24 bubble canopy version here)
and naval versions
Seafire Mk 3 (Spit Mk 5) first with folding wings
Seafire Mk 15 (Spit Mk 14)

and here Seafire 47 (Spit Mk24)
**Contra rotating props**
I could have done more and given more detail but way past my bedtime now...
Other even more nerdy Spit nuts might provide more (or tidy up some of my info) @AdAstraEU
a nicer photo of the PR19
the under wing *twin* radiators and 4 blade prop tell you it's a Mk 9 on the left.

@bencorke is maybe typical out there in claiming EU at fault for "Farage Garages" as is "negotiating in bad faith" (didn't Frost & Johnson, under pressure from Benn, in select committees both state opposite?)
Let's remind people of facts about border queues into the EU
Single Market only countries (Norway/Switzerland ) have long queues!
Custom Union only (Turkey) has greater queues!

On BOMB (Border Operating Model Bollox) I have no inclination to read it in depth but from what I have I see nothing new to prevent "disaster area" if not "disaster area with rocket boosters"..for me it just raises more questions? Where is the sufficiently trained competent staff
and facilities coming from for all these new sites? Even if they are available in *any* capacity? What about drivers' hours and transit times? Perishables? any slight delay/increased transit through these sites will render the shipments worthless. ICDs with BCPs should be as
close to port of arrival as possible: puzzled at how they will police/monitor driver accompanied loads to sites. More "smartfreight"? Joy! And don't see much on non specialist goods that make up majority of imports shipments.. SMEs are going to be overwhelmed with procedures

From a forwarder
"I made a precis of the UK’s ‘Border Operating Model, a 206-page document. Even the precis is 13 pages long & highly technical. I feel sure you probably can’t be bothered. It is difficult to read even for the experienced. More to t'point, it’s riddled with holes
So why bother? At least until those behind it wake up & smell the coffee. We have created basic process maps for what they are worth. Unfortunately, the Model displays such deficiencies that I was forced to use best guesses, the experience of my colleagues and myself and logic
to try to plug the gaps. The trouble is, those advising the government don’t appear to be using a lot of logic.
Neither do they seem to be asking the people on the ground who have the right knowledge? It is without surprise that it has emerged that version two of the Model

Ok so statements of the bleeding obvious that were somehow successfully dismissed as 'project fear' (now 'project here')

1/ leaving CU & SM will cause intractable problems over border in IRL. Automatic, now different customs & regulatory zones, border posts need to go somewhere
2/ leaving CU & SM means automatic need for greater space, staff & time for customs & regulatory processes at ports of entry/exit. (that UK doesn't have)

3/ leaving the CU means an extra 220m customs decs pa costs adding up alone to more than UK former EU annual contribution.
And to rules of origin complications far in excess of these costs

4/ leaving the SM means duplication of regulatory bodies & NTB/SPS compliance costs at vast expense, which combined with leaving CU (NTB) costs, meaning very obvious business job losses, contractions & failures

I sometimes hesitate to tweet for "fear" of repeating myself too much....BUT...I feel the need !!!
There are 145,000 UK businesses that will need to complete customs formalities for the first time on 1/1.
There will be an additional approx 230m customs declarations a year...
Needing that approx additional 50,000 customs staff (& 5000 customs officers) . It takes at least (with continued supervision) a year (I'm being optimistic) to train an individual to handle relative routine inquiries given complexity of customs entries/correct accompanying dox
esp on SPS.

Without long extended continued "transition", it is *impossible* (along with needed interfaced IT processes & necessary oganised infrastuctue/processing sites) for whole UK (not just NI) to be customs capacity ready for 1/1
(or even 1/7 for that matter IMO)

Further to Morrisons/Gibraltar .. from a friend "There is broader piece here about UK retailers supplying EU stores from UK warehouses, as many do at present. I know JD Sports is looking at ways to avoid potential of (eg) paying tariffs on trainers made in China on entry
to the UK, then again on entry into EU. Basically means building out distribution infrastructure in EU - Belgium seems a popular choice. And jobs there instead of jobs here. But hey, blue passports"
Their interim results statement: "We are very conscious that the UK's transition
period with the EU ends at the end of this year and, at this stage, there is a significant risk that the UK may exit that transition period with either no agreement or with perhaps just a very basic and limited free trade agreement. Given the current status of our supply chain
