Hi David     The Short frame were eithe  CG(600cc)  or CGP(750cc)  only

  when they went to long frame  it became DG and DGP  respectivly 

I have seen quite a few Long frame  retrofitted with CG/CGP and the odd short frame with Later engines    .  Al the same these are great small Scouts , 

Have a look at Jim Parkers site  he has  some info on Short frame Scouts of the 28  variety 

 Regards Phil

Hi David, the changeover was the first of  March 1928,  series 101 scouts engine numbers DG or DGP, the number sequence starting at 101. 

No official factory figures on production, I do not recall seeing a short frame CG or CGP number higher than around 1800 ? Anyone with any more info let us know.

There is also a distinct possibility that 1928 short frame models were still being sold overseas while the 101 was in production, as the factory used up available frames and parts that had already been made. Again, would love to hear about any specific info on this.  

My Short Frame is CGP  738   

Makes sense David. I owned cgp 373 for a few years, bouhgt in the US but it had been reimported from  Aus as a basket case. The short frame bobber I currently have , is around cgp1200 I think, but I bought the frame in Aus, the motor was US sourced tho.

Motors were identical to dgp 101s, just numbers different,  safe to assume that all short frames 28s had cg or cgp numbers. Interestingly, the late moodel little twins, that allegedly did not exist after 1915 , but were still for sale a couple of years later in Aus hade later  numbers, I think Pete Birthisel has one with a 1917 engine number. 

Anyone got a 28 shhort frame with what looks like an original front brake ? 

Anyone got one with an original looking 101 style dash and ammeter? What about the toggle light switch as opposed to the beavertail ? 

Anyone fancy sending in some pics and history of their short frame for the Wow? Be good to have a few more  details on short frames .

With an interest in the history/development of the early scout (model G) frame I was wondering if anyone has seen the 37 cu. in. (CG) motors with front engine pedestal mount in a 1928 short frame?  If I am correct (??), with the casings of the bottom end of the 37 cu. in. and 45 cu. in. being the same the through-bolt front engine mount configuration developed for the 45 cu. in. used in 1928 short frame could have been used for the 37 cu. in..  All 37 cu. in. motors in the 101 frame are through-bolt motor mount, correct??
