I've always liked the old GM design and wasn't big fan of the master grade GM profile.IMO that looks more like the GM II than the traditional GM. To my eyes HGUC GM had that old design and frankly if Bandai could do that with the HGUC I wondered why they could not re-do its MG GM with the version 1.5 tag like they did with MG Gundam.Anyhow enough for my rambling. Some time ago I became aware of B-Club conversion resin kit for the Gundam 1.5 and after some searching I was able to source it for good price. And I also so happened to have 1.5 kit that was partially used for another project but enough left overs to construct the necessary frame for the conversion.Looking at the conversion kit it replaces the head, cockpit hatch, front skirt as well as knee armours with calf pieces to accommodate the different profile of knee line. Oh yea there's also one-piece resin beam spray gun too. Now I'll be the first one to admit that the arm design of MG Gundam prior Perfect Gundam and Gundam OYW is piece-of-sh!t...And just so happened I picked up couple of HGUC-look conversion kits for MG Gundam from B-Club previously I decided to use the one with new arms that looked like HGUC ones. Obviously this new arms wouldn't have the same degree of movement as the OYW let alone the 1.5 but this GM wasn't for the mobility to start with. I'm going to build another one based on Gundam OYW frame for that.Another major disappointment was the one-piece head replacement. Sure it was casted with more traditional GM look but no clear visor? When HGUC kit came with the clear visor I couldn't use the resin head. Instead I cannibalized the master grade GM head instead. I did little bit of carving to make its face more HGUC look. If I had time I'd love to give the whole head more round look but given the time constraint I did what I could.Another part that was substitute was the beam spray gun. The resin part looks great - don't get me wrong. But its grip was too thin and without some modification I couldn't make the HDM to hold it properly when the beam spray gun from MG GM Kai kit worked just fine. (It's left over from the GM Spartan conversion in case you are wondering.) All it took was little bit of carving to convert the later type beam spray gun to early type beam spray gun.The B-club kit didn't provide the side skirt replacement and recommended to use the existing 1.5 side skirts. I replaced those with GM Kai side skirts. During construction, however, I did tried the GM parts but imho GM Kai parts looked better.Finally the last minute addition was substituting the waste area with the resin replacement. It's part of the B-Club conversion kit and after some debating - I did in fact built and painted both before deciding to use the resin replacement.Well that should be enough for my rambling. ^ ^ Here are some of progress pictures as well as instruction sheet in case anyone's interested.here are the very first partial build up. You can see the HGUC style shoulder armour plus how the front skirt will be attached. Also this build up had the ver. Ka style foot though I changed back to the original 1.5 parts.Here you can see that the cockpit hatch has been moved to the inner frame separated from the chest armour and rather botched attempt at the HGUC style chest vents.Here is the shot during painting process. I tried the subtle Max style shading and under the flash these were all gone so I took another one without the flash here and here.Upper torso frontArm unitFront skirt
