I should have waited 10 more minutes....and the Images would have been up!lmao.
No need for me Blumbly,You got it on the money,definately a Model 2...Everything confirms Rods assumptions on it being a model 2.
Going back to the original query of the engine no though. Id still maintain it as being Marine or industrial with this number. Its definately not a repairers mark,as ive seen before. A few years back i spoke to a bloke who had a lot of roto engines he was selling and he also had one with an X in the 200s and it was Victa Stamped as well,so I just thought it a bodgy,Since my conversation was by phone and I couldt see. Id only ever seen model 1s with this code.
Anyways, What engine? BMS as I said would be a close bet,BUT where to find one? I found a site a while back when looking for lawn cub stuff,and they seemed to know a fair bit about the company. Ill see if I can find the link

Also find out who posted that pic of the lawn patrols jonesy put up and go straight to the source,im sure they belong to a member off VM.
Hope youll keep that rotomo engine,would be a nice one to do up and maybee one day we can confirm what it actually came off for certain.....Im going with Marine:) Or you can always donate it to me! lols
