Mentioned these before, they came from an 1100 Lawson rep, any idea if they are standard, stamped ART and 181, can't see anything on crown, look quite decent so was going to put on ebay unless anyone here interested. Pm me for more pics if so, thanks

Now on ebay

ART are OEM pistons and if it's a genuine 1100R motor they will be Unitrack pistons.
The 1100R is essentially a Unitrack bathtub motor with carbs.
