So T2545 and W5352 are the same aircraft? I did not realize that. Why was the serial number changed? And it's not clear which mark the aircraft was initially completed as — or was it converted on the assembly line rather than after initial completion?
No idea why a new serial was allocated and there seems to be splits between those who say it is a Ic and a II, including having two aircraft cards, Ic and II. Take your pick, just make a note of your decision. I try to use first flown as but no information about this aircraft.
The conversions took place well after the aircraft were built, so I would consider them as a Mk 13 as originally built, with a note indicating it was later converted to Mk 10.
Agreed about the mark XIII and X, my mentioning of the mark X is for anyone wanting to double check my mark XIII conclusions, letting them know there were conversions.
I would just like to comment on the 175 Wellington I's. L4212 to L4391. If the five that were originally allotted to the RNZAF and not delivered (to the RNZAFin New Zealand)were added the total would be 180 for this batch, not 175. So can anyone supply information of the service in the RAF of L4312,L4313,L4314, L4315 and L4316 ? This is just one item as far as I am aware that has not been examined.
Good question, the answer is my comment about L4312 to L4316 was wrong and obviously wrong as MAP is only missing 2 mark I, the serials L4311 to L4316 were originally allocated to New Zealand but then all but L4311 were cancelled. No idea why, but it looks like R2699 to R2703 were the replacements. The note on the contract card with L4311 to L4316 says 6 for New Zealand with the 6 crossed out and replaced by 1.
NZDF Serials - Wellington Gives a list of New Zealand order serials. A contract card note says L4273 to maybe L4284 for New Zealand (end serial too faint to read clearly) after service test. Meantime L4273 to L4279 went to 9 squadron Feb/Mar 1939, L4280 to L4284 to 148 squadron in March, a total of 12 aircraft which the web site says were meant for New Zealand.
L4331, L4330, L4340, L4350, L4355 and L4360 have the contract card remark, for NZ contract 781439/38, indicating like the Hurricanes for Canada the New Zealand order was given its own contract number, with the RAF order(s) to be adjusted accordingly, the contract being for 18 aircraft, probably the 6 L serials and the 12 N serials listed at the ADF-Serials site and a good chance the P2515 to P2532 batch of 18 serials being their replacements, in some references being listed as contract 781439/38, which are all mark Ia while the contracts summary card says the order was 6 I and 12 Ia.
Of the N serials listed by the website only N2874 has a for New Zealand entry.
CHAPTER 2 — Early Operations from Britain and France | NZETC page 33 and
CHAPTER 4 — Outbreak of War with Germany and Initial Mobilisation and Training | NZETC page 1 indicates the offer to leave the NZ Wellington unit in Britain was in late August but no acceptance date was given. N2874 seems to be the cut off aircraft, in the second week of September 1939, after that the NZ order was simply part of the total Wellington Orders. The story being RNZAF orders 30 Wellingtons, 12 are to be transferred from RAF stocks but that does not happen before war is declared, 18 are under their own contract. Separate to this 5 of the 6 serials originally meant to be built for New Zealand are cancelled. Of the 18 L4330, L4340, L4350, L4355 and L4360 are marked delivered to Marham for New Zealand flight. Using the dates of the serials around them 2 came off the line in May, 3 in June, reported Wellington exports match this. L4311 only says New Zealand but does say it was to be NZ300. L4330, L4340, L4350, L4355 and L4360 have the date 14 November 1939 in their contract card entries, perhaps the date they officially rejoined the RAF, L4311 has 25 February 1940. Simple story in the end?
As an aside if war had not been declared the RNZAF could have had the Wellington Territorial Squadron operating from Wellington with Wellington bombers, perhaps finding a Squadron Leader Wellington to command it.
