Hi Colin I collect model electric motors I have 2 off BL Marines (square magnet) one in use and a BL geared upright permanent green painted magnet motor.
I have a variety of others, can you PM me a bigger picture of your mystery motor please? I can send my email address if that helps.
Just sold a SEL 1261 as new in a box as I was never going to use it.
Have a couple of the 1260's as well.
I have a lot of Marx motors mainly for use and one each of the Mabuchi 505 and a 705 in boxes. Just fitted a 505 into an old Bustler tug boat.
I have almost all the Taycols and exchanged a big one for a Decaperm ( for use). I also have an unusual Taycol 1:4 Taycol gearbox. I bought it in a surplus shop many years ago and they were stacked up high!
I have a 6v Hectoperm looking for a home as well.
A lot of the can motors maybe 70 or 80 altogether.
I found one of the BL Marine motors buried in a home made steering mechanism, that was out straight away and into a copy of the Sea Jay launch.
I also have one marine clockwork motor a big sturdy one 7/8ths. wide spring a K193. Saw one in a Kellner boat a week or so back at a Toy boat get together.
I have a couple of mystery motors as well.
