T-26 with a 120mm mortar

Post by Mangrove » 04 Jul 2010 17:24

I do not remember reading on this on any of the Finnish tank reference books although it is quite clear the project was abandoned after the 1944 attack. The mortar in question is perhaps Tampela's 120 Krh/40?

I have not heard about such project either, but there were some unusual projects going on around that time. The comments from 30th of June (by R. Lagus) and 8th of July (by G. Ruotzi) don't necessarily refer to that particular project. Also towing tractor version of T-26 tank called T-26V was under work that time. They were to manufactured by converting them from existing T-26 tanks, which according plans were to be replaced by more modern Pzkw-IVJ, T-34 and Stu 40G bought from Germany. While 10 - 12 T-26V had been ordered ultimately only three T-26 tanks were converted as such. Presumably T-26V were intended mainly as towing vehicles for 75 Pstk/40 antitank-guns (for towing which captured Komsomolets A-20 were somewhat small and weak).

This photo was posted on a Finnish forum. According to the original author it shows a prototype of the weapon at Niinisalo on July 25th 1944. The mortar is Tampela's 120 Krh/40.

Interesting! At the armor museum in Munster (http://www.deutsches-panzermuseum.de/) there is a post-ww2 APC of German make with a Tampella mortar: http://www.bredow-web.de/Panzer_und_Kan ... _kurz.html. Maybe Tampella managed to sell the concept after the war!

I would be willing to bet quite a lot of money, that the "type Tampella" mortar in that German vehicle wasn't manufactured by Tampella. We can also forget "selling the concept" - nobody in his or her right mind would have bothered to pay about it, since it could be easily copied for free. Patents might mean something - but this sort of technical concept is free for anyone to grab. German military had already used lighter mortars from half-tracks during World War 2, so I doubt it was much of a leap for German developers from there.

BTW: Practically none of "type Tampella" mortars used around the world nowadays were/are manufactured by Tampella and Tampella doesn't get any part of their profit either. The reason behind this is disastrous contract signed between Tampella and Salgad in year 1974, this contract gave Salgad all Tampella patents and at the same time limited Tampella's further mortar sales to Finland, while Salgad got the international market.

Jarkko, thanks for the info! Seems like Tampella is in the same situation as "Björn Borg" (he doesn't own his name as a trademark). There should have been a smiley after the "selling"!

Here are two photos I took by raising the camera and shooting blind into the vehicle. It looks a bit like a mock-up with a plastic tube.

best regards,
Lars
