Hey Unkie,
The mufflers are all technically correct.
The left is Rotomo aftermarket.
The centre is Rotomo Original" with original clamp and bolt.
The right is a later Replacement for the OEM muffler for Rotomo and also Original HG palmer 2 stroke utility. I think this style were around in the early 60s and onwards.
I wont attest to the flap being NON genuine as Ive never seen one before,but it looks well made... ( Also the screws and nuts arent period VICTA") Some HG Noble dept store Rotomos ran a flap set up but Im not sure if this is it. The later toe ring For Roto 2,2a and 3 you have probably seen im sure,and wrapped completely around the base. Ill check the HG noble and see if its similar,BUT Im not hopeful. Id put it on even if its not original for nostalgia, Run Victa 1/4 bolts and nuts,will look nice)The owner may have made it,and it shows initiative from the period
