WW2 bomb cradles

Thanks every one that’s brilliant!
As far as I know they came out of a scrap yard many years ago but as to what aircraft they were fitted to I have no idea? I presumed they were from a Lancaster or Halifax?

Avro Bomb Carrier

Flyingblind has posted a picture above which I saw some time ago when searching for information about bomb carriers on the internet. I don’t think it is as described – “Universal Bomb Carrier No. 1 Mark III ??”.

I posted this same picture on the Wreckage of Lancaster ED908 (60-Z) thread: http://forum.keypublishing.com/showthread.php?120747-Wreckage-Of-Lancaster-ED908-(60-Z)
at the top of page 40 in post #1172 showing the part numbers identified with the help of the owner. I believe it is, in fact, an Avro Type Bomb Carrier. Hence my request in post #2 above for confirmation of any visible part numbers. The picture does appear to be what is shown in the first three pictures posted by ballturret.

jamesinnewcastl kindly sent me a copy of AP1664 from which I have gleaned the following information:

The Universal (No.1 and No.2) bomb carriers were intended for use for 50lb to 500lb bomb loads;
the Avro Type (Standard) (Mk.I and Mk.II) was used for 100lb to 1,000lb bomb loads;
there was a Twin adapter, with two carriers on one unit, for the Avro Type for loads of 100lb to 1,000lb, with a maximum of 500lbs on each carrier, enabling four 500lb bombs to be carried abreast;
there was a special carrier for loads of 2,000lbs in the Lancaster;
Handley Page carriers for 250lb to 1,000lb bombs were used in the Halifax and Mosquito;
there was also a Twin adapter for the Handley Page carrier; and
there were other variations for loads of less than 1,000lb for the Halifax, Stirling and Wellington.

It therefore seems that the Avro Type (Standard) carrier would have been used in all British aircraft carrying loads with 1,000lb bombs other than those noted above which used the Handley Page version. AP2062A&C, the Lancaster parts listing, indicates that, as expected, the Avro Type carrier would have been fitted as standard to the Lancaster.

The attachment still fastened to the first carrier pictured appears to be a practice bomb attachment as shown in the diagram below from AP1664.

I can’t help with the heavy-duty casting on the second piece but, as suggested, it presumably was to adapt it to another use (perhaps for a heavier bomb load) but I cannot find anything illustrated in AP1664 which matches.

As Whitley_Project says, it would be helpful to have any history related to the carriers.

Is there any history with those bomb carriers ballturret?

Universal Bomb Carrier No. 1 Mark III ??
As per attached ?

Are there any part numbers visible, for example on the bomb release hook?
