German WW1 naval guns used in Liege forts 1940?

[daveh]

I am trying to discover the model of 150mm and 105mm guns used in the post WW1 modernised Liege forts.

The Belgians give the following details:
The 150mm gun is L/40 and an ex naval weapon
The 105mm gun is L/35 and an ex naval weapon
They were given to the Belgian Army after WW1

I was wondering if they might have been German coastal defence weapons based in Flanders.
Another possibility is that the 15cm and the 10.5cm guns were ex naval guns that the Germans had put on wheeled mounts during WW1

After a little research I found the following guns:

15 cm L/40 Feldkanone i.R.

10.5 cm SK L/35 in Räderlafette
based on

Can anyone provide more information on these weapons?
Are there any alternative guns you can suggest?
Does anyone know if these weapons were given to the Belgians post WW1?

Any assistance would be most welcome
Thanks in advance

Sadly I cannot help you out directly, but I can confirm that there were quite a few guns ordered for the forts prior to WWI from Krupps that were delayed in delivery as the war approached, and these guns would seem likely candidates for size. Presumably the order was completed post-war as part of the settlement by taking suitable guns from wherever possible.

Thanks for your reply Terry Duncan.

Following your comments about Krupp I have found that the original weapons mounted in cuploas used in the Liege forts were:
Krupp 15cm model 1886
Krupp 12cm model 1889
Krupp 21cm model 1889 and model 1891
Nordenfelt 5.7cm model 1888

All these guns were replaced during modernisation as follows:

The 150mm guns of the modernised forts were mounted in the old 21cm equipped cupolas.
The 105mm guns of the modernised forts were mounted in the old 12cm equipped cupolas.
A 75mm L/11 replaced the 5.7cm guns in the retractable cuploas.
The fort's central 15cm cuploas had their guns replaced by Maxim MGs and Lance- Grenades for local defence.

Glad you found them. I remember snippets of really odd bits of information from books read many years ago, its nice that they can prove useful!
