- Frame_weight_conflict
- The earlier 953 g value remains attributable to TanTan; current Seraph differs by 30 g without a documented explanation.
Current 32C T47/UDH listing retained separately from older BSA and separately titled 35C New-Version pages. Seraph now states 983±50 g while TanTan states 953±50 g at the same nominal basis; this is unresolved. Prices are foreign storefront references, not mainland totals. Public discussion links the 35C page but does not establish equivalence.
