Much thanks to EAIAnalog for this great clue for my continued work on Tail Enclosure research. It has answered a bunch of questions, but has now created a few new ones!!!
I have looked through the microfilm and am documenting the my research here:
The following has been extracted from Boeing Drawing: BODY INSTALLATION TAIL SECTION 45, Drawing 3-14335, original date December 16th 1942 and last update February 14th 1945.
I will note that this drawing is from Boeing, Seattle Washington. It includes details for both Boeing – Renton, Washington (REBAC on this drawing) and Boeing – Wichita, Kansas (WIBAC on this drawing).
BODY INSTALLATION TAIL SECTION 45, Drawing 3-14335 states that the following revisions were documented in this drawing:
Boeing Wichita, Kansas B-29 Production:Part Number 3-14335 was used on:XB-29
Part Number 3-14335-2 was used on: C/N 3325 YB-29-BW 41-36954 to C/N 3338 YB-29-BW 41-36967 = 14 Aircraft
C/N 3339 B-29-1-BW 42-6205 to 3350 B-29-1-BW 42-6216 = 12 Aircraft
Part Number 3-14335-4 was used on:C/N 3389 B-29-5-BW 42-6255 to C/N 3438 B-29-5-BW 42-6304 = 50 Aircraft
Part Number 3-14335-6 was used on:C/N 3351 42-6217 to 3355 B-29-1-BW 42-6221, 3357 B-29-1-BW 42-6223, 3359 B-29-1-BW 42-6225, 3360 B-29-1-BW 42-6226, 3361 B-29-1-BW 42-6227, 3362 B-29-1-BW 42-6228, 3368 B-29-1-BW 42-6234, 3370 B-29-1-BW 42-6236, 3372 B-29-1-BW 42-6238, 3373 B-29-1-BW 42-6239, 3374 B-29-1-BW 42-6240, 3375 B-29-1-BW 42-6241, 3376 B-29-1-BW 42-6242, 3378 B-29-1-BW 42-6244 to 3388 B-29-1-BW 42-6254 = 23 Aircraft 1st block of production
Part Number 3-14335-8 was used on:C/N 3489 B-29-15-BW 42-6355 to C/N 3538 B-29-15-BW 42-6404 = 50 Aircraft
C/N 3539 B-29-20-BW 42-6405 to C/N 3588 B-29-20-BW 42-6454 = 50 Aircraft
C/N 4081 B-29-25-BW 42-24420 to C/N 4130 B-29-25-BW 42-24469 = 50 Aircraft
C/N 4131 B-29-30-BW 42-24470 to C/N 4180 B-29-30-BW 42-24519 = 50 Aircraft
C/N 4181 B-29-35-BW 42-24520 to C/N 4230 B-29-35-BW 42-24569 = 100 Aircraft
Part Number 3-14335-14 was used on:C/N 4381 B-29-45-BW 24720 and on
Part Number 3-14335-16 was used on:C/N 4231 B-29-40-BW 42-24570 to C/N 4330 B-29-40-BW 42-24669 = 100 Aircraft
C/N 4331 B-29-45-BW 42-24670 to C/N 4380 B-29-45-BW 24719 = 50 Aircraft
Part Number 3-14335-18 was used on:C/N 3439 B-29-10-BW 42-6305 to C/N 3488 B-29-10-BW 42-6354 = 50 Aircraft
Boeing Renton, Washington B-29A Production:Part Number 3-14335-10 was used on:C/N 7231 B-29A-1-BN 42-93824 to C/N 7250 B-29A-1-BN 42-93843 = 20 Aircraft
C/N 7251 B-29A-5-BN 42-93844 to C/N 7280 B-29A-5-BN 42-93873 = 30 Aircraft
Part Number 3-14335-12 was used on:C/N 7281 B-29A-10-BN 42-93874 and on
Part Number 3-14553-8, 3-14553-12, 3-14553-14 and 3-14553-16 are cited on the drawing as being encompassed as a Revision M on this drawing dated January 10th 1944.
So this is a great clue and guideline for my research so far, but adds additional questions, for example that part number 3-14335-13 did actually exist, but is not reflected in this drawing. It does prove what revisions WERE used on specific blocks of production, and that the revision to the part 3-14335 was in fact not linear (-2, -4, -6, -8 etc) but was integrated at different non-linear blocks of production. This is consistent with my theory with Unit and Serial Numbers. So, Perfect!
This finding DOES PROVE my production theory, with: ASSY 3-14335-16 UNIT 528, Craft Number 11216, B-29A-45-BN 44-61739 (currently attached to “Jacks Hack” New England Air Museum B-29A-55-BN 44-61975), is in fact CORRECT!!!!!
Simply stated, this new finding clearly documents Part Number 3-14335 production up to February 14th 1945, for Boeing Wichita, Kansas produced B-29's up to C/N 4381 B-29-45-BW 24720 and Boeing Renton, Washington B-29A's produced up to C/N 7281 B-29A-10-BN 42-93874. This is AWESOME!!!!
