Please help me identify this servo
 

Hi all I need a new case for a ko propo servo but I dont know which servo it is as the sticker has come off.

measurements are 40mm by 38mm by 18mm.

I can post a pic later if that helps.

a pic would probably be best as most are a fairly standard size.

not sure if they have model numbers inside anywhere? you could try stripping it and having a look inside.
