Wade,
That’s a HUGE request, thats hundreds of pages, with original catalogues J2 and J3 perfect bound, thus cannot be properly scanned without damaging the book…
But you need to understand these three books J1, J2 and J3 cover 1-1/2 litre, 2-1/2-litre and 3-1/2 litre Mark IV primarily, but retrospectively also cover 1938-1940MY SS Jaguar including SS100 only. They do not cover/mention 1937 SS100 albeit there may well be some relevance in the 1938-40MY 2-1/2 litre coverage in J2.
Can I suggest that for matters Mark IV a far better forum is the dedicated Mark IV only Facebook group**: Jaguar Mark IV Lovers**
I suggest you join up……
The Facebook Group convenor Mateuz – he’s Polish, but for simplicity sake he uses the easier name Matt
Matt is in process of producing a large folder of all the Mark IV Technical Literature, including full copies of the J2 (2-1/2 litre) and J3 (3-1/2 litre) Spare Parts Catalogues being prepared apparently to break the bindings of his perfect bound originals to allow the pages to be flat scanned – I am not prepared to damage my ‘as new’ originals, so don’t have J2 or J3 personally scanned.
But these J2 and J3 SPCs by themselves only cover up to end of 1947 built cars – their publication date, not that that is a limit for your 1937MY 2-1/2 litre interest. There are separate Amendment Lists that extend these SPCs coverage up to the last Mark IVs built in 1949. There is also a separate Supplement JS.100 that details the later Single Helical Gearbox. J2 and J3 only cover the Double Helical Gearbox as fitted to 1938-40 SS Jaguar, and 1946-47 Mark IV.
There is a 1936-1937 SS Jaguar SPC, but its a descriptive list only, with no illustrations, and not much help at all. I have this 1936-37 SPC but again an excellent original, that I am not prepared to damage to scan.
I notice there is an original copy of this 1936-37 SPC currently listed on the latest Ian Cooling Auction JAC - auction is now open.
But if you want a full copy of J2, unless someone else can help, I suggest you join the Facebook group: Jaguar Mark IV Lovers and then access the huge Folder on all Mark IV Technical Literature being prepared by Matt…
