Squeezebores from other countries

[rigby]

My only squeeze bore I've got...... but I love her.:tinysmile_classes_t

I expect it to be quite rare....

the squeezebores shown by SG500 were loaded by colt in the 1960s.(in old cases for some reason)this project was developed by russel robinson(a new Zealander!) in the late 50s and early 60s.his company RICA,robinson improved conventional armament.there are 7 different versions of the 50 cal rounds(I have them all and will photograph them one day)
I cant find any record of who developed the one shown by rigby,could have been frankford arsenal as they experimented with loads of different rounds

Mine is described at HWS Vol.I p.263.

 

[kiwieod]

yes I have history of modern small arms and it describes the frankford arsenal test in 1942

Enclosed is a German 50mm the projectile is in bad shape but this is the only one I have come across so far.

Orcutteod,

You round looks like an Arrowhead, which is not a squeezebore.

So this would be the right configuration of projectile and
shellcase?

A photo off various 20mm littlejohn rounds.
The left hand round has the 117mm case length
The other 2 have the regular Hispano 110mm case length.

There's a good thread running about German squeezebores so I thought it was time to try and consolidate photos I've posted in various threads into one post in the hope others could share photos of their squeezebores. I use the term fairly loosely, in the UK they were referred to as littlejohns, elsewhere cone bore, the ones I'm showing are projectiles that get squeezed as the go down the barrel and exit with a far smaller diameter than they started.........so at the risk of boring you guys here goes, I hope you enjoy the photos, oh and if anyone has any spares in their collection I'd be glad to buy/swap:tinysmile_fatgrin_t................


20mm mystery.
This came from a Swedish collection, I know nothing about it but am of the opinion its real. Its made out of different parts with the flanges being put on separately.
Anyone any ideas?

The photos show a 37 x 222 unfired projectile next to a fired one next to a fired sectioned one.

40mm (2 pounder)
Two 2 pounder mark 2 littlejohns, one in section and one complete. These are the most common types out there (they're still hard to find).

40mm (2 pounder) and 40mm Bofors littlejohn. Both fitted with Mk 1 projectiles.
If it wasn't for the provenance of the Bofors I'd have said it was a made up round BUT a Bofors littlejohn was made and tested. Shown next to a mk 1 two pounder littlejohn for scale.

17 pounder
I think this is a 17 pounder flat head proof littlejohn. Its been fired without the attachment. I know of 1 other identical one in another collection.

ALL re INERT.

As I understand it, the Swiss developed the Janacek squeezbore system, mainly for bunker/fortress installations, 4.7 cm and 7.5 cm. https://www.festung-oberland.ch/
