Dear Datong,
Regarding Type Scrapper No.4 & 5 it is the same type between Short and Long (please check our attachment).
But we get just information from Mrs. Elly Tanudjaya that told us different as follow :
No. 4 = correct type (Scrapper Type Long K3740.18-1.0)
No. 5 = revison type (Scrapper Type Short K3740.18-1.4)
Please attention about this and we look forward to your reply the price. Thank You
Regards,
