there is nothing special you have to do to prepare your mangalloy frame. Elements such as manganese, molybendum & chromium are added in small quantities to steel to produce alloys which are stronger and more resistant to corroding. The name of yours indicates some manganese. But overall such a made up name means very little.
Your frame is steel and can be stripped cleaned of rust, and clear laqeur added to make a clear raw finish which would look good.
In terms of the whole peugout non-standard sizing. Cannot advise you with that, but im pretty sure you wont find somewhere that gives you all of the info just from serial number. The standards can vary hugeley.
