I've got the kit. It is the exact same kit as their twin turreted T-26 and single turreted T-26, just without the turrets. Even the twin and single turret upper plates are included (with the corresponding turret holes) but are listed as unused parts.
It's an old school Eastern European kit. Thick, flat parts that you have to carefully align. A gazillion delicate individual links on thick sprues. A lot of thick sprues containing mix and match parts. You use some parts off of one sprue, other parts off of another, etc. My sprues are mainly white with the suspension in a very light grey and one sprue in a bone/off-white color that you only use a couple parts off of.
I believe you can use the old Airwaves PE set for the 7TP and probably the old Eduard set for the T-26 (although that is for the Zvezda T-26) for generic grill details and such.
No decals included in my kit and the instructions are a front and back page of photocopied quality. Of the one page sheet front, top half is a parts layout with a brief description of the vehicle in Polish, the bottom half of the page is construction of the hull sides and suspension.
The back side of the page is instructions for the upper hull, tracks and superstructure, with the bottom half of the page showing the right side view of the vehicle with Humbrol colors H114 for the vehicle, H113 for the muffler, H53 for tracks and H67 for road wheels.
I bought mine maybe 10 years ago. It had a price of $19.99 and a clearance of $9.95, but I believe the owner sold it to me for $5-7 just to move it out the store. Never got around to it. I was tackling a couple other Eastern European tank kits and the experience sort of put me off from starting another. (Techmod T-50 and RPM TKS).
Modeling is about relaxation and fun to me. I found neither kit to be either fun or relaxing.
This is the box mine came in.
