Please help getting more information about a boat

[fredabik]

Hello,
I'm new on this forum and I think that meaby somebody should be able to help me....
I bought a boat last week and I would like to find out some more information about her.
She is a dinghy, more precisely an ELANCO LAPSTRAKE DINGHY, built by Landamore, as a plate inside is stating but there is no serial number anywhere.
The former owner believed it was from the 50's
I joined Landamore's and they confirmed they built her, they called her a Miss Mischief but they couldnt give me some more specifications, they axplained the lack of serial number by the fact that it was probably a dinghy for a larger yacht.
Does anyone of you know this type of boat, quite recognisable with her "cadillac" wings !!
