Lancaster Mk.X line drawings, specifically with the Martin turret


Recommended Posts

I've spent several hours Googling and going through the books I have on the Lancaster, yet have had no luck coming up with a set of line drawings for the Canadian built Lancs with the Martin turret. Does anyone know just where such a set of line drawings can be found? TIA.

I guess I was not clear on what I am looking for.

I am trying to find line drawings of Canadian built Lancasters that were fitted with the Martin turrets. I realize that these Lancs are very similar to the B.IIIs save for those that were fitted with the Martin turret. The Martin turret was positioned further forward and new external strengthening bracing was added to the fuselage around said turret. As such I hope to find a set of line drawings that will illustrate these differences as well as any other differences on the (upper) fuselage in particular (I suspect much of the rest of the aircraft was externally similar / identical to the B.III type) with respect to the Lancasters that were fitted with the Martin turret.

I do suspect that in order to accommodate the Martin turret other layout changes may have been made to accommodate it and that is what I am looking to find out.

So thanks for the B-26 reference, but it does not aid me at this time.

My conversion article Scale Aircraft Modelling Vol.17 No.2 April 1995 included some drawings....

I will hazard a guess that back issues are no longer available, would there be any chance that you are able to send a scan of your article or even the drawings?

Have you tried the Royal Australian Air Force Association Museum?

http://www.raafawa.org.au/museum/avro-lancaster.aspx

They currently have a Lanc VII on display with the Martin turret... would think they would be a good place to start.

The Canadian Warplane Heritage site has some pictures of a Mk VII with a Martin turret:

Perhaps, if you asked nicely........

That Canadian plane was just at the KIIKE airshow. I have few pictures of it if they would be useful. Mainly detail pictures, landing gear & bays, engines, bomb bay, rear quad turret, that sort of thing.

Hi Big Kohona,

what scale are you building in?

The Martin turret was fitted 6' forward of the original turret on the Mk.X also on the Mk.VII

In 1/72 thats 1" in 1/48 1.5". The turret from a Marauder will fill the bill,

though with no turret surround.

Something else to watch out for is the tail turret, as later production models

also changed this from the 4 X .303 F/N to 2 X .50 Rose turret,

with larger 'clear view panels' i.e. BIG holes!

The following may be useful:-

Hope this is useful, best regards,

Paul, I am building this in 1/72. Thanks for the measurements, definitely a BIG help.

I am still looking to see what other changes may have been made to accommodate the Martin turret.

I didn't realize that the rear turret was changed on some later models. I am guessing that there could not have been too many. I base this on what I have managed to find out about the Rose turret's .50 cal guns.

Although the twin .50s packed a bigger punch and had greater distance, the .303 Brownings were better suited to night bombing missions due to limited visibility at night and their rapid fire made them more effective.

There were two different rear turrets using the 50 cal guns on Lancasters. They were the Rose turret and the FN-82. The Mk VII used the FN-82 and is sprue Y on the Hasegawa Post War and Rescue Unit kits.

The Rose turrets were fitted to 150 Squadron and appeared in Oct 44. I believe that use was limited to selected squadrons in one group, (No.1 Group?) connected to proximity to where the turret was produced, I believe, but cannot locate the reference. It is different from the earlier 303 and later FN-82 turret. Hasegawa does not provide a Rose turret, as far as I can tell.

Here is a thread on Clean Blue, warbird forums, on Lancaster turrets comparing the Browning 303 and 50 Cal turrets, but it does not mention the Martin nor FN-82 turrets.

Interesting reading.

Best wishes,

Is Kohona a Canadian spelling? In Hawaii it was spelt Kahuna. No offense intended.
