SU-122 Assault Gun

SU-122 Assault Gun http://web.me.com/ethandunsford/DAK_PROJECTS/SU-122.html The T34 family of vehicles spawned many variants over its life. In response to the German practice of constructing assault guns on different tank chassis, the Russians developed the SU-122 howitzer based on the T34. While not effective in the anti tank roll, its 122 mm howitzer offered impressive fire power as mobile artillery and against fixed positions. Later SU variants included high velocity 85mm and 100mm anti-tank guns that proved more effective in the anti armor role. This project is a challenge due to a lack of any conversion kits or resin accessories to start with. I ordered the Imperial SU-85 conversion set from BYA for $85, but found it wasn’t suitable for my needs. http://web.me.com/ethandunsford/DAK_PROJECTS/SU-122.html#0 d639cc29-a75d-49e6-bdb6-8341c1633e32 http://web.me.com/ethandunsford/DAK_PROJECTS/SU-122_files/Media/DSCF0097.jpg?derivative=thumb http://web.me.com/ethandunsford/DAK_PROJECTS/SU-122_files/Media/DSCF0097.jpg?derivative=micro <div style="padding: 0px; " class="image_cluster_layout_style_default_External_177_16"><div class="image_cluster_layout_style_default"><p style="padding-bottom: 0pt; padding-top: 0pt; " class="paragraph_style_2">This project is a challenge due to a lack of any conversion kits or resin accessories to start with.  I ordered the Imperial SU-85 conversion set from BYA for <span class="style_1">$85</span>, but found it wasn’t suitable for my needs.</p></div></div> The gun mount and resin fighting compartment require more work to modify than I am willing to do. http://web.me.com/ethandunsford/DAK_PROJECTS/SU-122.html#1 5f320675-954d-4e26-9508-ca86f7b7fc88 http://web.me.com/ethandunsford/DAK_PROJECTS/SU-122_files/Media/DSCF0098.jpg?derivative=thumb http://web.me.com/ethandunsford/DAK_PROJECTS/SU-122_files/Media/DSCF0098.jpg?derivative=micro <div style="padding: 0px; " class="image_cluster_layout_style_default_External_177_16"><div class="image_cluster_layout_style_default"><p style="padding-bottom: 0pt; padding-top: 0pt; " class="paragraph_style_2">The gun mount and resin fighting compartment require more work to modify than I am willing to do.</p></div></div> I already had a WSN T34/85 tucked away and all I need now is another Trumpeter T34/76 for the upper hull and road wheels.
