Question about a kit from the mid-60s

Can someone here help me? Back in the mid-1960s, I was given a 1:72 kit of a Soviet PT/MTB … from my memory, the hull (deep blue plastic) reminded me of the Revell PT-109 kit. And the deck, again, from a little boy’s memory, was screwed, with tiny screws, to the hull. I’m thinking it was of a P-6 - But, I don’t remember … Does anyone know or remember this kit? And - no it was not the cheap kit which used the same hull of the Revell Higgins kit.

I’ve been told that it could possibly be a T3 Kosmolet type …

Nothing anything like that on Old Model Kits site.

You must have been living somewhere interesting.

I got the Revell 109 kit. Put me off PT’s forever.

I was just told it was by UPC.
