Hi folks,
Just out of curiosity really, I have tried to understand my Traveller's engine number code.
I found a couple of charts on the www but my number doesn't appear to fit with any of them! Just my flipping luck!
I have a 1275cc Marina (I think) engine & it is a Silver Seal recon.
The number is on a small plate, not stamped into the metal & is: RKM1128E 6704E.
Any info appreciated,
Cheers,
Andy.

RKM 1128E..is a replacement Silver Seal short engine (Unipart) number

'All engines pre-fixed with 'GSE' or 'RKM' were of UNIPART origin when BL split its parts organisation.'
'E' at the end of a part number denotes it is a reconditioned, service unit only (basic engine assembly with no ancillaries).
There are fairly good databases for the mini versions but I have not found reference to RKM1122E which is a minor engine reference.
My morris Traveller has engine No. RKM1121E.....and like yours is painted silver

GOLD/SILVER SEAL - WHAT YOU GET
Gold and Silver Seal engines differ in two ways. Gold Seal engines are applicable to vehicles up to five years old and contain a higher percentage of new parts. Silver Seal engines apply to vehicles over five years old and the lower percentage of new parts in these engines reflects the much greater availability of fairly good used parts for these slightly older engines. The sole exception to the 'five year old' rule is the MGB for which Gold Seal units are available rather than Silver Seal.
The same standards of re-manufacture apply to both types of engine except that the Silver Seal specification does not include the water pump, thermostat and thermostat housing and sparking plugs,(although plugs are to be included soon), but does include the oil pump and fiilter and crankshaft pulley. The Gold Seal specification includes all of these items and both types of engine will have been very thoroughly over-hauled. This work consists of stripping and thoroughly cleaning all internal parts, followed by close examination for wear, hairline cracks etc. Cylinder heads are checked and tested for compression. Crankshafts and camshafts are measured, reprofiled or reground to the same tolerances as a new engine and balanced. The maximum amount of metal which will be removed is 0.020" and any part which cannot be reconditioned within this limit will be discarded and replaced, often by a brand new component. After assembly every engine is set up , balanced, and "run for thirty minutes under power" (according to Unipart) during which time it is subject to inspection and testing for oil pressure, power output, smoothness of running and noise levels.
I have already referred to the greater availability of used parts for slightly older engines and the lower percentage of new parts used in Silver Seal engines. This is not to say that Silver Seal engines are in any sense a second class product. The same standards apply to both types of engine but in achieving those standards several engines may be stripped to provide parts which are capable of being reconditioned for a Silver Seal engines whereas fewer engines are available from vehicles up to five years old. Unipart aims to offer the same high standard in Silver Seal replacement engines and gearboxes but to do so at a lower cost to the customer. Gold Seal engines come with a 12 month unlimited mileage warranty, with Silver Seal the limits are 12 months or 12,000 miles. Both warranties state that if replacement or repair of the unit becomes necessary due to a manufacturing or material defect the unit will be replaced free of charge and the unexpected part of the original warranty will then apply.
In the day both Silver and Gold seal engines were widely regarded as being superior to standard production line units as the selective method of manufacture meant that you got an engine with closer tolerances, almost blueprinted in fact.
Wow, amazing answer, thanks Taupe!
My engine is definitely a 1275cc (with the spin-on oil filter on the side of the block, near the distributor).
The good folks on this site are a constantly amazing source of knowledge!

On Gold seal engines there is a stamped in code (not the raised code) on the engine number plate,both letters tell you firstly what the bore size is & secondly the crank size for eg 'A' 'H' is Standard bore with a 40thou crank each letter denotes the size,so first letter is bore size,second letter is crank size
A = STD
B =10THOU
C = 15THOU (crank only)
D = 20THOU
E = 25 THOU (crank only)
F = 30THOU
G = 35THOU (crank only)
H = 40THOU
J = 45THOU (crank only)
K = 50THOU
L = 55THOU (crank only)
M = 60THOU
So Your engine probably had FM = 30 thou rebore and 60 thou crank grind.....when it was rebuilt but of course could be anything now unless you got it still crated?
I now have this other engine out of the car & have found more numbers...any ideas what they mean/if they help identify the engine?
On one side of the block is 2A221 with AF3 underneath & what looks like 17 '8 '4 under that.
On the other side is what appears to be 1 /8/1/[frame][/frame]
