OK..my guess is that it can be a IMP airplane. IMP stands for Innovative Model Products. Originally out of NY they built planes with fiberglass fuselages and foam core wings back in the 70's and 80's. I recently picked up 2 of their P-51 D Mustangs that have the fiberglass bodies. IMP moved to Florida but still maintain a website. They do not make the fiberglass & foam wing core kits anymore!I have their website at home if anyone is interested in having it. Just email me at [email protected]. The guys helped me out on my P-51s. I needed plans and they were able to get them as well as an instruction booklet for working with foam core wings.
