Replacement Base for CALIBRATED Tamper - 49mm

This tamper head does not fit my existing LuxHaus tamper handle because the threaded portion is much too small. The advertised pictured item would work fine but that's not the one I received. An email sent to the seller after receiving this did not generate a response.ADDENDUM: Seller did contact me and is a class act (prior contact must've went to SPAM). Seller showed me the product that will fit tamper handle and I will order that base from Luxhaus (thank you). Seller was not asked to credit my account nor provide free replacement but did this of their own volition. This 58mm tamper head indeed has the narrow opening to accommodate a "calibrated" tamper handle so don't order this replacement base unless you've a handle that's narrower (see pic).

Had bought one of the 54mm calibrated tampers for a Breville espresso machine. When I upgraded to a new 58mm portafilter espresso machine I was looking at having to get a whole new tamper. This solved my problem.
